I would be very grateful for any references I might be led to, from a categorical point of view for the functors:


* $\textsf{Spec}\_{\mathscr{Z}\textrm{arisky}}(-)$, related to $\mathcal{O}(-)$, which leads to $\mathcal{O}(\textsf{Spec}\_{\mathscr{Z}\textrm{arisky}}(-))$,
* $\textsf{Spec}\_{\mathscr{G}\textrm{elfand}}(-)$, related to $\mathcal{C}(-,\mathbb{C})$, which leads to $\mathcal{C}(\textsf{Spec}\_{\mathscr{G}\textrm{elfand}}(-),\mathbb{C})$


These references would deal with "good" equivalences of categories, at the levels of algebraic geometry and operator algebras, which would be raised in a purely unifying categorical construction.


Many thanks in advance for any knowledge of books and articles written with this in mind.

In particular, dear @DmitriPavlov, thank you very much for your articles, your high categorical point of view and your answer, 01/13/2022, 11:51 p.m., to the internal question which prompted my question from personal research related to the relationship between Gelfand spectrum and Zariski spectrum, to which your answer to question : <https://mathoverflow.net/a/413776/502369> begins to reply.


You wrote this answer very brilliantly in terms of category theory and localization for this question of the relationship between the Gelfand spectrum and the Zariski spectrum, and the corresponding locales, topologies and sheaves, which therefore coincide in a more general setting .


I am also very sensitive to your arguments, Dear @DmitriPavlov, which appear in your article on Gelfand duality, stating the equivalences of categories with Hyperstonean spaces, Von Neumann algebras and three other categories, as well as in your text on category theory.


My first general question about possible references, therefore, continues, Dear @DmitriPavlov, with the following two questions, if you allow me to address you directly, but also to anyone who would be kind enough to answer them:


First :

Thank you in advance for your attention to my question and your interest in answering it.


Best regards

To the best of my knowledge, there is nothing published on this topic yet.
I once wrote some very rough unfinished notes on how to treat the algebraic, differential, and holomorphic cases simultaneously: <http://dmitripavlov.org/notes/cart.pdf>, which do discuss the construction of the spectrum and the structure sheaf, but do not go much further.
I am not sure how general this approach is, for example, I have not tried to use it with continuous and/or measurable maps, or connect it to C*-algebras or von Neumann algebras, although such a connection might exist. (I expect the construction of the structure sheaf to go through just fine for commutative C*-algebras and von Neumann algebras.)

That's a good question, and I am pretty sure the answer has not been written up (yet?).
In principle, it should not be too difficult to look at the construction of the Zariski spectrum and sheaf and abstract away the relevant properties that make the construction work. I would not be surprised if Malcev/protomodular/homological/semiabelian categories make an appearance at this point (see the book of Borceux and Bourn), since these are designed as abstractions of the usual categories of groups/modules/rings from algebra. But the precise conditions have not been pinned down yet, I think.
