37. March 11th, 2021
10 pm Beijing Time (GMT+8)
Speaker: Ruixiang Zhang , IAS, Princeton
Title: Local smoothing for the wave equation in 2+1 dimensions
Abstract: Sogge's local smoothing conjecture for the wave equation predicts that the local L^p space-time estimate gains a fractional derivative of order almost 1/p compared to the fixed time L^p estimates, when p>2n/(n-1). Jointly with Larry Guth and Hong Wang, we recently proved the conjecture in R^{2+1}. I will talk about our proof and explain several important ingredients such as induction on scales and an incidence type theorem.
38. March 25th, 2021
9 pm Beijing Time (GMT+8)
Speaker: Anna L. Mazzucato, Penn State University
Title: Mixing, irregular transport, and enhanced dissipation
Abstract: I will discuss transport of passive scalars by incompressible flows and measures of optimal mixing and stirring. I will give two applications , one is an example of complete loss of regularity for solution to linear transport equations, the others is a global existence result for the advective Kuramoto-Sivashinsky equation in 2 space dimensions.
39. April 8th, 2021
10 pm Beijing Time (GMT+8)
Speaker: David M. Ambrose, Drexel University
Title: Global existence results for the 2D Kuramoto-Sivashinsky equation
Abstract: The Kuramoto-Sivashinsky equation is a model for the motion of flame fronts. In one spatial dimension much is understood, including that solutions exist for all time. Analagous results in two dimensions are much more limited; most results in 2D assume that the domain is "thin," or approximately one-dimensional. We will give an overview of the results in one dimension and of anisotropic results in two dimensions. We will then show some global existence theorems for small data in two dimensions without making use of any anisotropy. This includes joint work with Anna Mazzucato.
