Mathematicians debate whether LLMs are filling the 'convex hull' of provable theorems

notmisha · x · 2026-11-06

Noah Chrein argues that LLMs, backed by the world's compute, are effectively filling in the 'convex hull' of standard mathematics — combinations of existing theorems and objectives that could have been proven but never were. What remains lies outside that hull, which massively favors trained mathematicians who know when new math must be invented versus pieced together.

The replies devolved into mathematicians arguing whether the correct abstraction is a convex hull, a semigroup, or a linear span — which the poster calls the most mathematician-possible response.
