Abstract: Motivated by Talagrand's conjecture on regularization properties of the natural semigroup on the Boolean hypercube, and in particular its continuous analogue involving regularization properties of the Ornstein-Uhlenbeck semigroup acting on integrable functions, we explore deviation inequalities for log-semiconvex functions under Gaussian measure.

Key words and phrases: Ehrhard inequality, Talagrand conjecture, Hypercontractivity, Ornstein-Uhlenbeck semi-group.
