KLS conjecture proved after decades; arXiv paper notes AI was used in the proof

felpix_ · x · 2026-10-06

A new arXiv paper (2610.05474) by Pierre Bizeul, Boaz Klartag and Joseph Lehec presents a proof of the Kannan-Lovász-Simonovits conjecture, one of the driving open problems of high-dimensional geometry alongside Bourgain's slicing problem. The key step builds on a recent criterion by Song and Zhang involving high-order derivatives of tilt averages. The 32-page paper explicitly notes it "contains a paragraph describing AI use"; multiple groups reportedly resolved it the same day, sparking wide discussion.
