内容摘要:

We will talk about a sharp lower bound for the fundamental gapdefined as the difference between the first two eigenvalues of the Ornstein-Uhlenbeck operator under Dirichlet boundary conditionsover convex domains in Gaussian spaces. Furthermore, we establish a closely related sharp super-log-concavity property for the corresponding Dirichlet heat kernels. This talk is based on a joint work with Jin Sun of Fudan University.
