This template has all of the macros I have found useful in the past 4 years of my undergrad. I got most of these macros from my REU mentor Prof. Raul Gomez. This should be useful for anyone doing algebra/topology/algebraic geometry/geometry/category theory or anything else using diagrams. Also has some useful templates for theorems, lemmas, observations and proofs. It has all of the standard things that mathematician need in her preamble, like hyperref, amsmath, all the packages that are used for commutative diagrams, and much more.
This latex template is acceptable by the University of British Columbia for MSc or PhD theses. It has been transferred to OverLeaf by Naba Mukhtar, and slightly updated in 2021 by Leah Edelstein-Keshet
