Dear all,

I would like to announce the following talk that will be held on Thursday January 16th 2020, at 4:30 PM, in Aula Dal Passo of the Department of Mathematics, University of Rome Tor Vergata.

Speaker: Maria Gordina (University of Connecticut)

Title: Stochastic analysis and geometric functional inequalities

Abstract: We will survey different methods of proving functional inequalities for hypoelliptic  diffusions and the corresponding heat kernels. Some of these methods rely on geometric methods such as curvature-dimension inequalities (due to Baudoin-Garofalo), and some are probabilistic  such as coupling, and finally some use structure theory and a Fourier transform on Lie groups. For nilpotent groups, the latter can be interpreted as an eigenfunction expansion of the hypoelliptic heat kernel. This is based on joint work with F. Baudoin, B. Driver, T. Melcher, Ph. Mariano.
