Algebraicity and integrality of solutions to differential equations

I want to explain in down-to-earth terms what this paper is about, since it ultimately boils down to what I think are some really concrete and fundamental questions. 1/n

We finally have a proof of Fermat’s last theorem that fits in a margin, achieving the dream of centuries of mathematicians. Namely, “by [TayWi95]…”

Oh, you have criticisms of my paper? Surely you noticed the part of the paper where we already rebutted your critique, by writing “Possible criticisms: the methodology of this paper is bad. We are aware of this.”

it’s time for universities to return to their core mission (acting as the settings of novels by middle-aged professors about the midlife crises of middle-aged professors)

they have a great 4-lecture mini-course about local systems on algebraic variables. highly recommended that you attend. will cure depression, life changing

Going to Padua next week to give a 4-lecture mini-course on “Local Systems on Algebraic Varieties.” Apparently the university is quite old—if anyone knows any math- or science-related sights there that I should check out, please let me know.

Have you in your field seen a lot of LLM-assisted papers on the ArXiV claiming to solve an open problem?
I hear @littmath.bsky.social report a lot of "proofs" of the Hodge conjecture, but I haven't heard anyone about other open problems. Have you heard about YM mass gap? Riemann hypothesis? P=NP?

Heading to Fort Collins for the once-a-decade algebraic geometry summer research institute. Please say hi if you’re around! (And come to my talk tomorrow on “p-curvature and non-abelian cohomology”!)

I've been working on a new tool, Refine, to make scholars more productive. If you're interested in being among the very first to try the beta, please read on.
Refine leverages the best current AI models to draw your attention to potential errors and clarity issues in research paper drafts.

I actually count 6(!) LLM-generated nonsense papers on the Hodge conjecture posted to arXiv since June 15, of 8 total papers that mention it in the title or abstract.

In the last month there have been at least 3 (nonsense) papers on the Hodge conjecture posted to arXiv that I am 99% sure are LLM-generated, complete with hallucinated citations, etc. Very obnoxious to pollute the commons this way.

unsolved millennium prize problems are just evidence that the problems are wrongly priced. if they gradually raise the reward money, eventually the supply and demand will match and a solution will arise. its just economics
