A Gaussian small deviation inequality for convex functions
Grigoris Paouris, Petros Valettas
Let be an -dimensional Gaussian vector and let be a convex function. We show that: $$\mathbb P \left( f(Z) \leq \mathbb E f(Z) -t\sqrt{ {\rm V…
Probabilistic Condition Number Estimates For Real Polynomial Systems I: A Broader Family Of Distributions
Alperen A. Ergür, J. Maurice Rojas, Grigoris Paouris
We consider the sensitivity of real roots of polynomial systems with respect to perturbations of the coefficients. In particular - for a version of the condition number defined by…
An interpolation proof of Ehrhard's inequality
Joe Neeman, Grigoris Paouris
We prove Ehrhard's inequality using interpolation along the Ornstein-Uhlenbeck semi-group. We also provide an improved Jensen inequality for Gaussian variables that might be of ind…
An inequality for moments of log-concave functions on Gaussian random vectors
Nikos Dafnis, Grigoris Paouris
We prove a sharp moment inequality for a log-concave or a log-convex function, on Gaussian random vectors. As an application we take a stability result for the classical logarithmi…
