Joshua Grochow: Can one do "algebraic geometry" over a monoid in place of the coordinate ring? That is, suppose I have a commutative monoid. Is there a coherent (in the informal sense) notion of Zariski topology? …
Joshua Grochow: (Answers would be great, but I'm more looking even for keywords, authors, etc to look up - hard to search for.)

Berna Devezer: i cannot wrap my head around that 2 papers a week (socarxiv) or a month (arxiv) should constitute a meaningful cap on preprint submissions. 2 papers a year (no one) though? that i'd get.
David Marx: They probably picked that threshold based on the current percentiles to try to at least "desk reject" the worst offenders. powerlaw effect as usual: it's likely a minority of bad actors are committ…
