Gaussian lower bounds for the density via Malliavin calculus
In this paper, based on a known formula, we use a simple idea to get a new
representation for the density of Malliavin differentiable random variables.
This new representation is particularly useful for finding lower bounds for the
density.Comment: To appear in Comptes Rendus Mathematique, 10 page
An improved bound for the Gaussian concentration inequality
In this note, we provide an improved bound for the Gaussian concentration
inequality. Our proof is short and bases on the integration-by-parts formula
for the gaussian measure.Comment: 4 page
