@Fish_CTO A geometric perspective: if you know a bit of differential geometry, probably you know that the curvature measures precisely the commutativity of the derivatives. In this sense, by saying that the partial derivatives commute in R^n, you are geometrically saying that R^n is flat.
New wiki feature: we introduced a system of auto-hyperlinks to other wikis, as nLab, Wikipedia and Stanford Encyclopedia of Philosophy. The autolinks will be added according our needs, but you can help with suggestions: https://t.co/xNujJycd5K

Thank you,

Math-Phys-Cat Group.
Dear all. Since the creation of our group, we had no financial support. Every cost and every activity was provided by our members, including costs with hosting and maintenance of the website/wiki, organization of events, and so on.
Part of the donations will be used to move our website/wiki to a better server, and also to organize the hybrid version of the 2nd Brazilian Meeting in Category Theory.
Professor Hugo is himself the leader of a group on Category Theory and Logic in IME-USP. We expect that this is an important step to strengthen and unify the field in Brazil.
Just to recall that our news are shared not only here, but also in our website (https://t.co/tE1D02di6p), where they are more detailed explained. You can also receive our news directly in your email: send an email to [email protected].
We created a page in our group website as a honor to Fábio Dadam (our member that died one year ago). There you will find some additional information about him and his relation with our members.

In February 2021 we organized with UFES the 1st Brazilian Meeting in Category Theory. We are happy in saying that we are now starting the first discussions to organize the second edition, now in hybrid format, with IME-USP! More details soon.
Since Math-Phys-Cat Wiki is a modified version of Pmwiki, its markup was originally the Pmwiki markup, which is incompatible with latex. Now the Math-Phys-Cat Wiki is much more compatible with latex, recognizing essentially all fundamental latex environments.

Olá pessoal! Aos que falam português e se interessam por física e matemática, os nossos seminários sobre Mecânica Quântica Axiomática estão no nosso YouTube: https://t.co/jwUmS430yr
We are happy to announce new features of Math-Phys-Cat Wiki, including the possibility to turn a page into a pdf that looks like a LaTeX pdf!

They all work and collaborate in mathematical aspects of quantum mechanics and quantum information. They will join Raphael in our Research Subgroup on Mathematical Quantum Mechanics.
