order differential equation: and can be solved exactly (at least in theory). The method is easily generalized to higher order equations. For functions of several variables, a generalized Wronskian is a determinant of an by matrix with entries (with ), where each is some constant coefficient linear partial differential operator of order . If the functions are linearly dependent then all generalized Wronskians vanish. As in the 1 variable case the converse is not true in general: if all generalized Wronskians vanish, this does not imply that the functions are linearly dependent. However, the converse is true in many special

so on through the th derivative, thus forming a square matrix sometimes called a fundamental matrix. When the functions are solutions of a linear differential equation, the Wronskian can be found explicitly using Abel's identity, even if the functions are not known explicitly. If the functions are linearly dependent, then so are the columns of the Wronskian as differentiation is a linear operation, so the Wronskian vanishes. Thus, the Wronskian can be used to show that a set of differentiable functions is linearly independent on an interval by showing that it does not vanish identically. It may, however, vanish at

cases. For example, if the functions are polynomials and all generalized Wronskians vanish, then the functions are linearly dependent. Roth used this result about generalized Wronskians in his proof of Roth's theorem. For more general conditions under which the converse is valid see . Wronskian In mathematics, the Wronskian (or Wrońskian) is a determinant introduced by and named by . It is used in the study of differential equations, where it can sometimes show linear independence in a set of solutions. The Wronskian of two differentiable functions and is .

moneyers who struck coins during this period acted under the auspices of the king, who would to some extent have supervised the design of his coins. A growing shortage of available bullion in north-western Europe during the first half of the 8th century was probably the main cause for a deterioration in the proportion of precious metal found in locally produced sceattas. In around 740, Eadberht of Northumbria became the first king to respond to this crisis by issuing a remodelled coinage, of a consistent weight and a high proportion of silver, which eventually replaced the debased currency. Other kings

The last category of whistleblowers/accusers was individual analysts both well known in the industry and anonymous accounting for 10 accusations. In the years from 2010 to 2011, it was noted that 62 CRM’s were accused of fraud by these eventual short sellers. In the presence of the fraud accusations, whistleblowers/accusers began to aggressively short these CRM companies. The short sellers were vital in being fraud detectives into these CRMs and the main motive was behind exposing the faulty financial

Pet Parade on the Saturday of the festival, usually from mid-morning to early afternoon. Children will decorate their bikes, and families will put their pets in their best costumes and parade them throughout the downtown area. The festival also hosts the "Grayslake's Got Talent" contest. The final parade of the festival, the Summer Days Parade, generally kicks off on Saturday evening. Similar to Grayslake Days, Taste of Grayslake is held in late June (usually the weekend prior to Independence Day) in Grayslake's Central Park. This festival's primary purpose is to showcase all of the local food vendors Grayslake has to

is located south of the Cuernavaca and was established by Hernán Cortés as one of the first sugar plantations in Mexico. Descendants of the Conquistador held the property until the 19th century, when it became the property of Lucas Alamán, who modernized the facility. The hacienda lost its surrounding properties during the Mexican Revolution and all that remains is the main house. After a long period of restoration and modification, the hacienda today houses an exclusive hotel, which can accommodate conventions and banquets. South of the city center is Acapantzingo, which had been a separate town, but now is part

William Samuel Lilly William Samuel Lilly (10 July 1840 – 29 August 1919) was an English barrister and man of letters. Lilly was born at Fifehead, Dorset, in 1840. He was educated at Peterhouse, Cambridge, taking his degree of LL.B. in 1862, and his LL.M. in 1870. After some private tuition from Sir Adolphus William Ward, he entered the Indian civil service, becoming in 1869 secretary to the government of Madras. Owing to a breakdown in health, however, he had to return to England, where he devoted himself to a career in literature. With his wide-ranging intellectual interests, Lilly occasionally

increase on the second test. If your favorite sports team won the championship last year, what does that mean for their chances for winning next season? To the extent this result is due to skill (the team is in good condition, with a top coach, etc.), their win signals that it is more likely they will win again next year. But the greater the extent this is due to luck (other teams embroiled in a drug scandal, favorable draw, draft picks turned out to be productive, etc.), the less likely it is they will win again next year. If one

c runs over a complete set of direction vectors, made specific by having the last non-zero entry equal to 1, i.e. In particular the Moore determinant vanishes if and only if the elements in the left hand column are linearly dependent over the finite field of order "q". So it is analogous to the Wronskian of several functions. Dickson used the Moore determinant in finding the modular invariants of the general linear group over a finite field. Moore matrix In linear algebra, a Moore matrix, introduced by , is a matrix defined over a finite field. When it is a

He said that he does not condone the actions of either organisation: "Does it mean I agree with Hamas and what it does? No. Does it mean I agree with Hezbollah and what they do?

If this is all [Lilienfeld] mean[s] by the analogy between society and an organism, there seems to be no objection to pursuing it to its utmost extent and determining how far social functions resemble organic functions, recognizing all the time that there is no real morphological or structural resemblance any more than there is between the wing of a bat and that of a bird. What, then, does Senator Lilienfeld mean by his oft-repeated expression, "real analogy"? Does he mean that here are homologies? It seems

not give the employee proper consideration or used improper criteria for the promotion. Each employer should know the distinction between what is unethical and what is illegal. If an action is illegal it is breaking the law but if an action seems morally incorrect that is unethical. In the workplace what is unethical does not mean illegal and should follow the guidelines put in place by OSHA, EEOC, and other law binding entities. Potential employees have ethical obligations to employers, involving intellectual property protection and whistle-blowing. Employers must consider workplace safety, which may involve modifying the workplace, or providing appropriate
