Abstract:

We prove a quantitative version of the Gaussian Faber-Krahn type inequality proved by Betta, Chiacchio and Ferone for the first Dirichlet eigenvalue of the Ornstein-Uhlenbeck operator, estimating the deficit in terms of the Gaussian Fraenkel asymmetry. As expected, the multiplicative constant only depends on the prescribed Gaussian measure.

Keywords: first Dirichlet eigenvalue, Gaussian analysis, Faber-Krahn inequality, Ornstein-Uhlenbeck Operator
