A 35-year-old Cypriot nationwide Guard captain is with in custody dealing with multiple homicide fees.

“I felt obliged to accomplish one thing for those females, most of the lacking ladies, all of the killed females,” protest organizer Maria Mappouridou stated. “I think deeply down, all that we wish, exactly what everyone desires, is justice.”

Federation of Filipino businesses in Cyprus seat Ester Beatty stated she hoped the function, plus the tragedy associated with fatalities, raise awareness that is public migrant employees. Continue reading “Vigil in Cyprus for 7 Missing Women, Girls; Suspect in Custody”

Bio Chemistry Secrets That No One Else Knows About

For instance, if you should sum four numbers to acquire a total, you have the freedom to decide on any numbers you prefer. The greater density of dots indicates the physical location where the electron cloud is the most dense. There are five units of concentration that are especially helpful to chemists.

As its name implies, biochemistry can be thought of a mixture of biology and chemistry. http://www.columbia.edu/cu/badminton/ Analytical chemists want to develop increasingly accurate and sensitive procedures and instruments. Biochemistry is a broad and multidisciplinary area of study that could lead to a lot of diverse kinds of careers.

Degree checklists aren’t official. Generally, it is suggested that students earn no less than a graduate degree to be taken seriously as a scientist. You’ve got to balance the chemical equation no matter what, according to the Law of Conservation of Matter, but a lot of students find it tough to balance it.

A lot of different tags are developed to help researchers purify certain proteins from complex mixtures. The liver is a complicated organ. Although there are various kinds of cells, most cells have the very same components.

There are two main approaches to understand when the solution was neutralized. The quantity of strong acid or base a buffer can neutralize is known as the buffer capacity. This process is known as deamination.

The length of the program is three decades. Scarce and out-of-print materials could be obtained through https://buyessay.net/book-report interlibrary loans from across the country. For that reason, it can’t be digested.

Rumors, Deception and Bio Chemistry

Normality is very beneficial in titrations calculations. Equations often contain terms besides the unknowns. Furthermore, balanced equation is essential in determining how much reactant you would have to have, for making the particular item.

As stated by the Fisher equation, the nominal interest rate is equivalent to the sum of the actual rate of interest and inflation. Again, it’s better to write down whatever you know into an equation. While there isn’t a certain number of constants you must identify, remember that if designing an experiment, you’re going to be assessed on how well you had the ability to control the variables to make reliable data.

The chemical or pharmaceutical salesperson needs to be prepared to travel a good deal, servicing existing accounts and finding new clients. To put it differently, the curve moves based on the terms of the reaction. Frequently, these are not easy to balance.

The nominal rate of interest is the sort of interest rate that is measured before thinking about the inflation in an economy. Nonetheless, the catalysed reaction is still likely to be a whole lot faster than the uncatalysed one due to the tremendous increase in sufficiently energetic molecules. This one is simple, since you maintain the quantity of solute the exact same and only have to change 1 factor.

What Is So Fascinating About Bio Chemistry?

There aren’t any books that cover the whole syllabus of IIT JAM. As you’re very likely to explore dimensional analysis a little more as you take science courses, it can be especially valuable for Biology students to find out more. In the last year of the Biochemistry course, students also work a protracted first term to start their research undertaking.

A PhD is important for academic research or maybe to secure a career as an academic lecturer. Small businesses employ biochemists to supply specialist solutions, such as toxicological studies. They will be required to submit a final report describing their leadership activities and experiences.

The interdisciplinary course is designed to support first-semester students and supply them with a foundation for university success. Moreover, excessive increase in the liquidity can often result in a greater rate of inflation which can further bring about hyperinflation. This contributes to the ideal assignment service it’s possible to acquire on the internet to help you achieve maximum grades.

Evaluate what happened, dependent on the hypothesis and aim of the experiment. It would be hard to overstate the significance of the role biochemistry plays in all our lives. Therefore, the fundamental relationship among them may be determined by the essence of their work.

Polyethylene is a difficult, durable good material quite different from ethylene. Although ceramics are very hard and stable at quite significant temperatures, they are generally brittle. The very first compound was completed as an example.

When bromthymol blue is in the existence of a base, it’s blue. Carbon is an element you may be acquainted with. Combustion reactions release large quantities heat.

It attempts to explain them in chemical stipulations. Order of a reaction is a significant parameter for every single chemical reaction. These reactions may be spotted, since they will always involve the exact reactants and products with varying coefficients and subscripts.

There can well be 30000 times more molecules that may react, but it’s highly possible that the frequency factor will have changed in the existence of the catalyst. The goal of this chemistry science fair project is to figure out the way the temperature of a combination of water and ammonium nitrate changes with the quantity of ammonium nitrate dissolved in the water. A good example of a normal electrode is silver chloride.

BoDog SUCKS Cheating Bastards – CLOSING Account – STAY AWAY

Anybody considering Bodog, better believe TWICE!!!!
Here we go with the 3rd time they tried to CHEAT me and have cheated me this last time.
On May 3 I put in a wager at the Conclusion of the 3rd for $20 to get Miami minus the things. After it processes it reveals this bet: Date placed: May 03, 2011 7:56p Date settled: May 03, 2011 8:17p Bodog Live Number 213737410 (Placed by Web) Will the total points scored by the Celtics from the 3rd quarter be odd or even? Boston Celtics at Miami Heat (3rd Quarter 12:00) “Actually” -115 Mon@11:00p I ask and call wtf happened? They as usual say they don’t cancel wagers. Then I have to fight together point out the wager shows 3rd Quarter along with also the 3rd Quarter is finished. How do I place a wager to get a 3rd quarter bet if the 3rd quarter is finished. In addition, I ask would I actually be that stupid to put a wager that was not on the board for the wrong side? Also the time reflects the 3rd Quarter has been completed. Now for now…I had taken Dallas for the match at another book and following the 3rd Quarter when the Lakers were 6 up, thought now would be the time to quash my Dallas to the Game wager, so I set a wager for$25 on LA -5.5 -101. The moment I click the wager it shows processing and then comes back and says”Line was upgraded to Lakers +103″. I look at the base of the page and no open bets. On top my balance is the same, so I click on the button to make the bet. After it is accepted, the bottom of the screen shows 1 open wager, yet my account balance reveals they took both bet.
Back on the phone, speak to the rep, and put on hold for a manager, then hung on. Phone back and go through the same moves and get on the telephone together with the Supervisor. I explain to them what happened and she says they do not cancel wagers. I told them about what happened 2 days earlier and I ask why you are trying to deceive me to get your cash? Once more I am told they don’t cancel wagers, but she will make a exception should I put a bet for $25 on another game and after that they’d charge the one wager back. If I don’t the one won’t be canceled. I mean seriously, is that the right method to get some of their money back? Do they actually think I am that dumb I can’t enter$50 or 25 and when their system is just taking 2 wagers rather than the one that I won’t call and say anything? Pathetic!
Now I go back and question that when this first happened during my first week of drama and that I was stuck using a wager, that a notice was put in my account that every time a double bet happens immediately like this, that the final was to be removed if it were at precisely the same time. Did they respect this, NO? Are they CHEATING me, YES!
I am just glad it is their money I was playing , but it is such BULLSHIT, which they’re attempting to deceive people this way. Are they getting hurt that bad that they need to CHEAT YOU? Therefore by forcing me to make a play without completing my study that that will satisfy my for their mistake?
Insert in that early this week I had issues with their site and the site had been telling me to call them. They want me to put wagers to get a $50 minimum on the phone. Some game I will wager that more and a few I simply make a little wager to maintain my addiction going. They do not need me to e-mail them a screen shot of this error message and just keep saying we have no reports on our conclusion. I want Pinnacle would take US Players….by far the very best book I’d. The Greek is also another good one, but they’ve made adjustments to withdrawals and deposits, so I was searching for one more book. BOY DID I CHOOSE WRONG!!!!!! Should have just dealt with the tried Betus or some thing. I’ve NEVER has any issues like this with a book earlier. NEVER! When there was a problem, it was corrected as long as I called when the mistake was created, which I did in this situation. The 4th didn’t even start and that I missed the whole damn thing whilst on the phone together. Needless to say, once the wager I was made to Place for tomorrow is completed, my money is coming to me and I am closing my account! No Longer from this Cheating Novel. And as far as this site recommending them and using them at the TOP 5 is Complete Horse garbage!!! They should be removed from the website and not even recommended or used. I will be filing a complaint to the gaming board their in Canada, but I am pretty certain it’ll mean garbage! But to anybody else who is searching for another book, do not utilize BoDog by any way unless you would like to keep dealing with a problem of type weekly or so. Should you insist on using them, be wise and look over your wager once placed and display shot each screen for your defense so that you have some proof and then it can be submitted someplace to shows these Dirty Cheating Procedures they like to use. I am just happy I only put$40 to test out how these guys are and not the normal \$500 like I usually do. I guess when you’re up over 15 times your first deposit and have a bad day, they simply try to make it worse. I will update here in order to observe the way their payout goes on to see if I get a bounced check or when one comes.

Fantastic Latin Brides – Individuality, Dating, Marital relationship

## Conjectures about q-de Rham complex: examples

Peter Scholze formulated several conjectures about $$q-$$de Rham complex here. Especially intriguing to me is Conjecture $$3.2$$: Betti-de Rham comparison isomorphism.

In this paper the author emphasized the lack of nontrivial examples and suggests to do a computation for the universal family of elliptic curves.

Question 1: Has anyone done this computation (or any other interesting computations)? I will be especially interested in those involving basic hypergeometric functions.

Question 2: What does conjecture $$3.2$$ mean in practice? Naively one might hope that it leads to some $$q-$$deformation of periods.

## Leafwise de Rham cohomology(A true definition of Differential forms along leaves)

For a foliated space $$(M, \mathcal{F})$$, one associate a leafwise de Rham cohomology. This cohomology and trace class operators on this cohomology and trace interpretations for closed orbits of certain flow on $$M$$ is the main object of this paper”Number theory and dynamical system of foliated manifolds.

But in the later paper, I did not find a very precise definition of “Differential forms along leaf”.

So I try to find other papers or talk to find a precise definition for this concept. Then I found a definition at page 8 of this talk “Lefschetz trace formula for flow on foliated manifolds” which give a local representation for such forms. But my problem is the following:

I think that such representation, which is quoted below, is NOT invariant under foliation charts:

$$\omega\sum_{\alpha_1<\alpha_2<\ldots<\alpha_k} a_{\alpha}(x,y) dx_{\alpha_1}\wedge dx_{\alpha_2}\wedge \ldots\wedge dx_{\alpha_k}$$

Am I mistaken?

What is a precise definition and precise local representations of “Differential forms along leaves”?

## Is there literature on a de Rham analogue of the Mumford-Tate group or ell-adic monodromy group?

Let $$X$$ be a smooth projective variety over $$\mathbb{Q}$$. The theory of motives predicts that for each cohomology theory, there should be a distinguished Zariski closed subgroup of $$GL(H^k_{\bullet}(X))$$, the motivic Galois group. This group has conjectural descriptions for Betti and $$\ell$$-adic cohomology, and I am wondering if there is any literature on this group for de Rham cohomology.

The Betti cohomology $$H^k_B(X)$$ is a rational Hodge structure, hence there is a representation $$\mathrm{Res}_{\mathbb{C}/\mathbb{R}}\mathbb{G}_m\to GL(H^k_B(X)\otimes\mathbb{R})$$. The Mumford-Tate group $$MT^k(X)\leq GL(H^k_B(X))$$ is defined to be the smallest Zariski-closed subgroup containing the image of the representation. The Hodge conjecture would imply that $$MT^k(X)$$ has finite index in the Betti motivic Galois group.

The $$\ell$$-adic cohomology $$H^k(X;\mathbb{Q}_\ell)$$ is a representation of the absolute Galois group, and the $$\ell$$-adic monodromy group $$G_\ell^k(X)\leq GL(H^k(X;\mathbb{Q}_\ell))$$ is defined to be the smallest Zariski-closed subgroup containing the image of the representation. The Tate conjecture would imply that $$G_\ell^k(X)$$ is the full $$\ell$$-adic motivic Galois group.

Is there any literature on an analogue of the Mumford-Tate group or the $$\ell$$-adic monodromy group inside $$GL(H^k_{dR}(X))$$?

I believe that a conjecture of Ogus would imply that the de Rham motivic Galois group is smallest Zariski closed subgroup whose $$\mathbb{Q}_p$$ points contain $$F_p$$ for all sufficiently large $$p$$ (where $$F_p\in GL(H^k_{dR}(X))(\mathbb{Q}_p)$$ is the crystalline Frobenius). However I have some doubt about this, because André’s book on motives states the relationship between the Hodge conjecture and the Mumford-Tate group (Proposition 7.2.2.1), and the relationship between the Tate conjecture and the $$\ell$$-adic monodromy group (Proposition 7.3.2.1), but does not give an analogous statement for the Ogus conjecture.

I also believe that the period conjecture of Grothendieck would imply that the de Rham motivic Galois group is the smallest Zariski closed subgroup containing all elements $$\varphi\in GL(H^k_{dR}(X))(\mathbb{Q})$$ whose image in $$GL(H^k_{B}(X))(\mathbb{C})$$ under the Betti-de Rham comparison isomorphism is contained in $$GL(H^k_{B}(X))(\mathbb{Q})$$. However, I also cannot find a statement like this in André’s book.

## Exterior Product on de rham homology

Given a smooth manifold $$M$$ and its differential graded commutstive de Rham algebra $$(\Omega(M),d,\wedge)$$, the wedge product $$\wedge$$ can be projected onto the de Rham cohomology $$(H_{dR}(M),\wedge)$$.

What is an elegant way to proof that the wedge product is, indeed, well defined on $$H_{dR}(M)$$?

## Equivalence De Rham und Dolbeault Groupoids

I believe there is an error or incompleteness in Goldman’s and Xia’s Proof on the equivalence of the De Rham and Dolbeault Groupoids.

In page 33 of https://www.math.umd.edu/~wmg/higgs.pdf they want to proof that $$Mor(D_1,D_2)\to Mor(S(D_1),S(D_2))$$ is bijective.

They do that by proving that $$Mor(D_1,D_2)$$ and $$Mor(S(D_1),S(D_2))$$ are either $$\varnothing$$ or $$\mathrm{C}^*$$ depending on whether $$D_1$$ and $$D_2$$ (or $$S(D_1)$$ and $$S(D_2)$$) are equivalent.

This however does not exclude the possibility that $$Mor(D_1,D_2)\to Mor(S(D_1),S(D_2))$$ is actually the empty morphism $$\varnothing \to \mathrm{C}^*$$. For that they would need that $$S_*$$ is injective, but they do not proof that, in fact that is the purpose of the Corollary 4.1.10

Am I getting something wrong? How can I proof that $$S_*$$ is injective?

## De Rham cohomology and extension of scalars

Let $$K$$ be a field of characteristic zero and let $$X$$ be a smooth variety over $$K$$. Given a field extension $$L/K$$, I denote by $$X_L$$ the variety $$X \times_{Spec(k)} Spec(L)$$.

What is the easiest way to prove that algebraic de Rham cohomology behaves well with respect to this operation, in the following sense? $$H^\ast_{dR}(X) \otimes_K L \simeq H^\ast_{dR}(X_L)$$

## Serre spectral sequence for de Rham cohomology

Suppose we a given a fibration of manifolds $$p\colon E\to M$$ with a path connected fiber $$F$$ and simply connected $$M$$, then we have the Serre spectral sequence with

$$E_2^{p,q} = H^p(M,\underline{H^q(F)})$$

The standard proof of its convergence to $$H^n(E)$$ is purely topological and goes for singular or cellular cohomology. Can one give the proof in terms of de Rham cohomology?

In fact, I’m even more interested in de Rham cohomology with compact support. Now we have some difficulties in defining the local system as cohomology with compact support are no longer homotopy invariant but I hope these problems can be overcome.

## Notational question on Kunneth Formula for de Rham cohomology

I got to learn the Kunneth Formula for de Rham cohomology as following.

$$H^n(X\times Y)=\sum_{n=p+q} H^p(X)\otimes H^q(Y).$$

And I could find same notation from https://www.encyclopediaofmath.org/index.php/K%C3%BCnneth_formula.

Actually, it is quite unfamiliar to use $$\sum$$ for spaces. I think it should be $$\oplus$$ instead of $$\sum$$. It might be stupid question and maybe I am wrong and missing something. I am looking for some clarification for it!

And clear explanation for this would be appreciated! Thanks in advance.

# Investigating the Koch Snowflake

Extracts from this document...

Introduction

Mathematics HL Portfolio

Omar Nahhas.

Class 12 “IB” (C).

The Koch snowflake is also known as the Koch island, which was first described by Helge von Koch in 1904. Its building starts with an equilateral triangle, removing the inner third of each side, building another equilateral triangle with no base at the location where the side was removed, and then repeating the process indefinitely.

The first three stages are illustrated in the figure below

Each step in the process is the repeating of the previous step hence it is called iteration.

If we let Nn = the number of sides, ln = the length of a single side, Pn = the length of the perimeter, and An = the area of the snowflake, all at nth stage, we shall get the following table for the 1st three iterations.

Table no.1: the value of Nn, ln, Pn, and An, at the stage zero and the following three stages.

 n Nn ln Pn An 0 3 1 3 (√3)/4 1 12 1/3 4 (√3)/3 2 48 1/9 48/9 10(√3)/27 3 192 1/27 192/27 94(√3)/243

Note: assume that the initial side length is 1.

We can see from the above table that the number of sides isn multiplied by four at each iteration.

Middle

= 3(16),   N3 = 3(64)

N0= 3(4)0,  N1=3(4)1,   N2=3(4)2,    N3= 3(4)3

Hence, Nn= 3(4)n

Length of a single side (ln)

As we proceed in each stage the length of any side is 1/3 the length of the side from the preceding stage. If we begin with an equilateral triangle with side length 1, then the length of a side in nth iterations is

ln = 1/ (3)n

For stage 0 to 3, ln = 1, 1/3, 1/9 and 1/27.

Or as in the above it can from the value of ln from the zero stage till the third stage

l0=1, l1=1/3, l2= 1/9, l3= 1/27

l0=1/ (3)0, l1=1/ (3)1, l2= 1/ (3)2, l3= 1/ (3)3

And hence ln = 1/ (3) n

Perimeter (Pn)

Since the lengths of every side in every iteration of the Koch Snowflake are the same, then perimeter is simply the number of sides multiplied by the length of a side

Pn = (Nn) (ln)

Pn = (3(4) n) (1/ (3) n)

For the nth stage.

Again, for the first 4 steps (0 to 3) the perimeter is 3, 4, 16/3, and 64/9.

As we can see, the perimeter increases by 4/3 times each iteration so we can rewrite the formula as

Pn = 3(4/3) n

Or it can be derived from the value of Pn from the zero stage till the third stage

P0= 3, P1= 4, P2= 48/9,P3= 192/27

Conclusion

As n increases the area converges to a certain value where that the 1st six decimals are equal in the successive terms, and such patterns beings to appear at stage number seventeen where that A17= 0.691693219 and A18= 0.691693719, so we can see that An+1 = An to six places of decimals at n=17. For the other values as n get larger there is no value of n where that ln = ln+1 to six places of decimals.

The perimeter as n → ∞ the perimeter becomes very large going to infinity, and the area converges to 0.692820323 which is equal almost to (8/5) ((√3)/4) which is (8/5) the area of the original triangle at step 0.

Hereby the general expression for An will be proved by induction

A0= (√3)/4, A1= (√3)/3

An = An–1 + (1/3) (4/9) n–1((√3)/4) prove it is true for n=1

A1 = A1–1 + (1/3) (4/9) 1–1((√3)/4)

A1 = A0+ (1/3) (4/9)0((√3)/4)

A1 = (√3)/4+ ((√3)/12)

(√3)/3 = (4(√3)/12) = (√3)/3

Then Left hand side equals Right hand Side

Now assume it is true for n=k that is

Ak = Ak–1 + (1/3) (4/9) k–1((√3)/4)

Now we want to prove it is true for n = k+1

Ak+1 = A (k+1)–1 + (1/3) (4/9) (k+1)–1((√3)/4)

Ak+1 = A k+ (1/3) (4/9) k((√3)/4)

A1 = A0 + (1/3) (4/9)0((√3)/4)

(√3)/3 = [(√3)/4] + (1/3) ((√3)/4) = (4(√3)/12)

= (√3)/3

Since An is true for n=1, so it true for n=k, then it true for n= k+1, then is true for all values of n

# Meaning of diffeomorphism invariance?

1. Mar 17, 2008

### kdv

I initially posted this question in the Beyond the Standard Model forum since diffeomorphism invariance is a key ingredient of loop quantum gravity but it was suggested that I post the question here.

Why is Einstein's theory diffeomorphism invariant? A diffeomorphism is basically a map of the points of the manifold into other points of the manifold so the points are actually moved and the manifold gets distorted (which is totally different than a coordinate transformation in which the points are not changed but simply relabelled).

At first, it seems impossible for GR to be invariant under an arbitrary mapping of the points. Consider a region of space very far from any mass/energy distribution. GR would say that this region is near flat. But if we can perform an arbitrary mapping of the points, what prevents us from transforming this region into a region where there is a nobn-zero curvature? (which would clearly violate Einstein's equations).

So does it mean that there is some well-defined restriction on the allowed mappings? But this never seems to be mentioned...

Or am I completely misunderstanding what diffeomorphism invariance means?

When you move points around you also have to 'bring' the geometry along with you, so everything is ok. It just means that there is no absolute location (or the absolute coordinate system) in spacetime. Suppose the spacetime is a plane, and suppose you have chosen some coordinate system on this plane. And suppose that a massive object is near the origin, and another massive object is at (0,1). Then, by diffeomorphism you can move these objects to, say, points (10,10) and (100,23), of course you also have to transform the geometry of the plane appropriately. Then the underlying physics will not change, the physics is only in the relative position (or geometry) of these points, it is not whether we have the point (0,1) or (100,23). Remember the coordinate system is not changed, only the geometry changed, so these coordinate values can identify the points on the mathematical manifold.

Thank you. I am still a bit confused so let me ask more questions.

First, what do you mean by "you also have to bring the geometry along with you"? This is the part that confuses me. So we are not free to map the points to anything we want. For example, I can't map part of the plane to a curved surface, right? (I mean, I can't generate a "bump" in the surface through the diffeomorphism). I am not sure how this type of restriction is implemented mathematically. what is a definition of a mapping of points that "brings along the geometry"?

A secodn question is about the fact that the coordinate system is not changed so as you say the coordinates of the points changes. So this means that the metric must change too when a diffeomorphism is applied, right? Otherwise it seems that physical resultys would be changed. SO my question is: what happens to the metric during a diffeomorphism...am I right that it gets transformed? And if so what is the definition of the transformation law of the metric through a diffeomorphism?

Thank you very much.

Diiffeomorphisms are the active versions of passive coordinate transformations.

If $\phi : M \rightarrow M$ is a diffeomorphism and $p \in M$, then $\phi$ can be used to shift all geometric objects, including the metric tensor, at $p$ to corresponding geometric objects at $\phi\left(p\right)$, either by pushing forward with $\phi$, or by pulling back with $\phi^{-1}$.

In particular, $\left( M , g \right)$ goes to $\left( M , \phi_* g \right)$, where the new metric tensor $\phi_* g$ "acts" at $\phi\left(p\right)$ like $g$ does at $p$.

Everything actively shifts, vector fields, metric, curvature, etc. This shift is represented by new objects at, for example, $\phi\left(p\right)$ that "act like" the old objects at $p$.

Now let's start adding a bit of detail. To do this, generalize to $\phi : M \rightarrow N$, where $\phi$ is smooth but not necessarily a diffeomorphism. For example, $\phi$ might not even be invertible.

Consider a scalar field $f : N \maps \mathgbb{R}$ on manifold $N$. Define the scalar $\phi^* f : M \maps \mathgbb{R}$ (think of it a as all one symbol for a function) on $M$ by $\phi^* f := f \circ \phi$. The function $\phi^* f$ has the same value at $p \in M$ that the function $f$ has at $\phi\left(p\right) \in N$, i.e., $\left( \phi^* f \right) \left(p\right) = f \left( \phi\left(p\right) \right)$.

The smooth mapping $\phi$ has been used to pullback the function $f$ on $N$ to a new function $\phi^* f$ on $M$. Note that because the compositions don't work out correctly, $\phi$ cannot be used to push forward a function $h : M \rightarrow \mathbb{R}$ to a new function on $N$.

Now, on to vectors, covectors, and tensors.

Thanks George. I did not reply earlier because I needed time to mull this over (and was busy with midterm tests). I think that very slowly things are making more sense. But I still have ways to go.

The above sentence makes sense. I used to think that "mapping of the manifold to itself" meant mapping of, say, a 3-manifold to any 3-manifold. But now (if I understand correctly!) one is actually mapping points of the manifold to other points already there in the manifold, right? Then that makes much more sense to me.

So, to check my understanding of what you said let me ask this: one way to generate a diffeomoprhism is to do the following: one may relabel the points of the manifold with new coordinates (at this point the manifold has not been changed in any way, just the relabelling). A second step is now to map the points of the manifold (with their new coordinates) back to the points which had the same coordinates before we relabeled the points. Is this correct?

Does this have any physical content? I am curious because this diffeomorphism invariance is a bid deal in LQG. I guess that the point is that if one sums over manifolds, one must treat the manifolds related by diffeomorphism as gauge equivalent.

This works beautifully when it can work, but circumstances don't always allow it to work.

For example, consider the plane $\mathbb{R}^2$ with Cartesian and polar coordinates. Given a point p, it's not always possible to find a point q such that polar coordinates of q equal the Cartesian coordinates of p.

More abstractly, a coordinate system on an n-dimensional manifold $M$ is a bijective smooth mapping from a "bit" of $M$ to a bit of $\mathbb{R}^n$ such that the mapping's inverse is also smooth. In general these bits of $M$ and $\mathbb{R}^n$ aren't all of $M$ and $\mathbb{R}^n$; a number of coordinate systems may be required to cover $M$.

More formally, a coordinate system on an n-dimensional differentiable manifold $M$ is a diffeomorphism $\psi: U \rightarrow \psi\left[U\right]$ between an open subset $U$ of $M$ and an open subset $\psi\left[U\right]$ of $\mathbb{R}^n$. So, for $p \in M$, $\psi\left(p\right)$ is an n-tuple of real numbers, the coordinates of p.

Now suppose we have two coordinate systems between all of $M$ and all of $\mathbb{R}^n$, $\psi: M \rightarrow \mathbb{R}^n$ and $\psi': M \rightarrow \mathbb{R}^n$. Then $\psi^{-1} \circ \psi' : M \rightarrow M$ and $\psi'^{-1} \circ \psi : M \rightarrow M$ are diffeomorphisms of $M$. For example, let $\phi = \psi^{-1} \circ \psi'$ and $p \in M$. The $q = \phi\left(p\right)$ is also in $M$, and $\psi\left(q\right) = \psi'\left(p\right)$, i.e., the coordinates of q in one coordinate system equal the coordinates of q in the other coordinate system.

This formalizes (maybe overly so!)your nice idea.

If my points are particularly obtuse or compressed, let me know. I don't think things would seem as abstract if we could stand together with appropriate tools in our hands (chalk!) in front of a chalkboard.

Thanks for your reply. It is starting to make a whole lot more sense to me now.
I am glad to see that my (admittedly very rough and unsophisticated) idea was in th eright ballpark
This makes a lot of sense!! I guess I always need a very concrete picture of something before understanding the more formal (and complete) description. Even if the concrete picture is not completely general, it gives me an "anchor" to build the more general formalism around, you see what I mean?

So, if I understand correctly, the maps $\psi$ and $\psi'$ you are talking about must absolutely map the whole manifold to $\mathbb{R}^n$, right?
We can't work with patches only? This seems to me a big problem because then it would sound as if it is too restrictive. For example, consider the surface of a sphere (a plain, two dimensional euclidian surface of a sphere). There is no map that covers the entire manifold, right? So does that mean that we can't have any diffeomorphism in that case?

That would be great but this is already much clearer in my mind, thansk to you. It's just that I am slow and I need to have a concrete picture in my mind before grasping the more formal approach. Thanks a lot, again. I hope we can soon discuss general coordinate transformations vs Lorentz symmetry in GR as well.

Is my set up correct?

x + y + z = 775,000
.08x + .09y + .10z = 67,500
z= 4x
Since you picked x to be "the amount borrowed at 8%" (and z to be "the amount borrowed at 10%), the last equation should read x = 4z.
