I am comfortable with the use of group theory, but am looking for the right starting level textbook/review article for category theory and it how it "meshes" with groups (for physicists), if you could recommend something, please
This is from "Excitations in strict 2-group higher gauge models of topological phases" by Bullivan and Delcamp. Physicists are starting to use 2-groups - categorified groups - to create mathematical models of new topological phases of matter. https://arxiv.org/abs/1909.07937 pic.twitter.com/4jeHTamOjU

Whew, that's kind of hard because this subject is too cutting-edge. Do you know gauge theory?

i offer $100 for the latex source. weaponized binaries for windows machines not sought, thanks all!

The LaTeX source is freely available for all papers on the arXiv: just click on the link I provided, then find "other formats" and click on that.

Do you think this is a new evolution in the application of categorized-groups since i am not in touch as much. in my phys days , group theory usage was common , but looking at the paper, lot of new notations cropping up in new physics
-
What's new is that condensed matter theorists are starting to use 2-groups to imagine new kinds of matter, which eventually they can try to make in the lab.

In case someone knows: Is there something that makes drawing 3D diagrams like these easy, or is this plain TikZ? Because that looks quite impressive!
-
This looks pretty straightforward using xypic, except for the dots with various shades of gray, which I've never used. I don't know if it was done with xypic or TikZ.

I don't know anything about what that diagram says, but it looks so beautiful. I'm excited to understand it in some future and appreciate it even more
