Ill be giving a minicourse for the next three weeks at the Topology, Geometry and Physics seminar tomorrow at 9am EST on my notes “Coverages and Grothendieck Toposes” (arxiv.org/abs/2503.20664), see www.zeinalian.com/workshop for more info!
Coverages and Grothendieck Toposes
These notes detail the basics of the theory of Grothendieck toposes from the viewpoint of coverages. Typically one defines a site as a (small) category equipped with a Grothendieck topology. However, ...

There are way too many categories of graphs, this is ridiculous. Most of them aren’t even toposes 😒

Is $\mathrm{Graph}$ cartesian-closed?
Let $\mathrm{Graph}$ be the category of simple, undirected graphs with graph homomorphisms. For any graphs $G, H$ we denote by $\text{Hom}(G, H)$ the set of graph homomorphisms $f:G\to H$. (Note th...

Goodreads is owned by Jeff Bezos. A better alternative is StoryGraph, a Black woman-owned platform. And before y’all start, you can transfer all your Goodreads data to Storygraph so you literally have no excuse.

Also, I've been building a category theorist starter pack on BlueSky: go.bsky.app/Qe38ctW
I added you to it to hopefully help build out the CT network here. Let me know if I am missing anyone!

Its been a while since I tried social-mediaing but this place seems interesting, so lets give it a try. I’m Emilio, I am an Assistant Professor of Math at CUNY CityTech and I study category theory. Lately I’ve been learning about algorithms and thinking a lot about sheaves.
