Topic: What are categories of modules over semirings?


view this post on Zulip Brendan Murphy (May 18 2024 at 17:21):

Modules over (associative, unital, not necessarily commutative) rings form abelian categories, and abelian categories are tightly connected to module categories (via Freyd-Mitchell, Gabriel-Popescu, etc). We can tell a similar story for stable infinity categories and modules over E1 ring spectra. What sort of general class do semiring module categories fit into? This is a hazy question, but I hope it makes sense what I'm looking for. Probably this comes down to something like "what exactness properties are true of the category N-Mod of commutative monoids"
