Talks Fall 2021:

Currently on Zoom, see links below for each talk. The Zoom sessions are open from 3:45pm (15 minutes before the talk begins) for discussion.


Friday Oct 8th 2021 (4-5pm): Homogeneous Solutions of Stationary Navier–Stokes Equations with Isolated Singularities on the Unit Sphere I.

Speaker: Yanyan Li (Rutgers)

Abstract:  We present some existence and classification results on axisymmetric homogeneous solutions of stationary Navier–Stokes equations with  singularities at north and/or south poles.  We will also study asymptotic stability of some of these solutions. These are mainly joint works with Li Li and Xukai Yan.

Friday Oct 29th 2021 (4-5pm):Landau damping and echoes in plasma physics

Speaker: Toan Nguyen (PSU)

Abstract: The talk is to give an overview on the classical notion of Landau damping discovered by Landau in 1946, which will in particular highlight recent mathematical advances on understanding the damping and the large time behavior of a plasma, including (1) an elementary proof of the nonlinear Landau damping for analytic and Gevrey data and the construction of large, but damped, echo solutions (joint work with E. Grenier from ENS Lyon and I. Rodnianski from Princeton) and (2) nonlinear Landau damping in the weakly collisional regime for a threshold of initial data with Sobolev regularity (joint work with S. Chaturvedi and J. Luk from Stanford).
