Tilt-stable log-Sobolev conjecture for log-concave measures
Tilt-stable log-Sobolev conjecture for log-concave measures
Let be a log-concave probability measure on . It is -tilt-stable if, for every , the covariance operator of the tilted measure is bounded by in operator norm, where is the normalized tilt of by . Tilt-stable log-Sobolev conjecture. If is a -tilt-stable log-concave probability, then
The source states this as a weaker consequence of the preceding log-Sobolev KLS conjecture, using that tilt-stability implies sub-Gaussianity up to a universal factor. Its general validity remains open.
