Title

On vacuum boundary with physical singularity

for compressible Euler equations--old and new

Abstract

In this talk, I will first review the background and challenge and known results in the study of physical vacuum of compressible inviscid fluids. Then I will discuss the problem of global in time behavior for the system with damping including the old joint work with Prof Huihui Zeng and some recent developments. Lastly, I will present the recent joint work with Dr. Sicheng Liu on the local well-posedness in low-regularity weighted spaces in Hadamard sense for full compressible Euler equations in multi-dimensions.

About the Speaker

Professor Luo received his PhD from Chinese Academy of Sciences in 1995. He held a professorship at Georgetown University before joining the City University of Hong Kong. His research interest is mainly in nonlinear partial differential equations and analysis, including: Mathematical Analysis of PDEs of Fluid Dynamics, Fluids Free Boundary Problems, Hyperbolic Conservation Laws, Calculus of Variations and etc.

A constructive proof of finite time blowup of 3D incompressible Euler equations with smooth data
Abstract：Whether the 3D incompressible Euler equations can develop a finite time singularity from smooth initial data is one of the most challenging problems in nonlinear PDEs. In this talk, we will present a new exciting result with Dr. Jiajie Chen in which we prove finite time blowup of the 2D Boussinesq and 3D Euler equations with smooth initial data and boundary. There are several essentia...
