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.
This seminar is part of the activity of the MIUR Department of Excellence Grant 2018-2022, CUP E83C18000100006.
Kind regards,
Anna Vidotto
