报告题目: Regular and Singular Structures in Fluid Dynamics and Differential Geometry

报告人:李思然 博士上海纽约 大学

报告时间:2020929日下午200-300

报告地点:汇星楼514                       

报告内容:We shall report our recent work on the issue of regularity vs. singularity in two distinct realms: fluid mechanics and analysis on manifolds. By exploring connections between geometric structures and fluid motions, we provide novel insights into several classical problems in geometric analysis and mathematical hydrodynamics. More specifically, we shall discuss our progress on the existence and compactness of isometric immersions of manifolds, regularity criteria for the Navier--Stokes equations, and elliptic estimates on Riemannian manifolds. Throughout these topics, ''wild'' spirals and oscillations play a central role in our constructions.

报告人简历:李思然,2017年获得英国牛津大学数学博士学位,导师为陈贵强教授;2017--2020年在美国莱斯大学跟随Robert Hardt教授从事博士后研究;现任上海纽约大学访问助理教授。研究主要方向为偏微分方程、微分几何与整体分析、流体力学,以及在工程和物理问题中的应用。2018年被选为蒙特利尔数学研究中心CRM--ISM postdoctoral fellow2019年获得加拿大Kolmogorov--Wiener Prize for Young Researchers
