PDE Seminar via Zoom

Updated: 5 days ago

Organizer: Quoc-Hung Nguyen, Institute of Mathematical Sciences, ShanghaiTech University, Shanghai, China.

The Seminar's purpose is to promote and influence more cooperation, understanding, and collaboration among scientists working in Partial Differential Equations.

Due to the coronavirus pandemic and in a time of social distancing, PDE Seminar via Zoom aims to provide such a venue for the PDE community, and keep as many researchers as possible stay connected.

How to use Zoom:

  • The seminar will take place over Zoom. Please download and setup Zoom via link: https://zoom.us/download

  • Please log in with your real name.

  • About one day before the seminar, the link, meeting ID and password to join the Zoom meeting will be attached here.

  • Audiences can use "Raise Hand" on the chat window to ask questions to the speaker.

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.
