Negative moments of the support function and applications to isotropic convex bodies
Antonios Hmadi, Dimitris-Marios Liakopoulos
We study lower tails of support functions of isotropic convex bodies. An endpoint negative moment estimate, combined with a spherical cap argument, gives polynomial deviation estim…

Moment comparisons, Sudakov inequalities and entropy of centroid bodies
Antonios Hmadi, Dimitris-Marios Liakopoulos
Let be an isotropic log-concave random vector in and let be standard Gaussian. Starting from the first moment comparison for gauges, we derive corresponding…
