A sub for everything in pure mathematics.
All posts, and all comments, must all be about pure mathematics.
Discussions of applications of pure mathematics can occur in the comments.
No post is allowed to contain anything other than pure mathematics (e.g. it is not allowed to be about applications of mathematics, reactions to it, etc. E.g. it is allowed to be about Fourier transforms, a mathematical derivation, questions of mathematics etc.)
Logic is considered a part of pure mathematics in this sub.
