报告题目与摘要:


Degenerate Elliptic Equations and Subsonic-sonic Flows in General Nozzles

王春朋(304永利集团官网入口)

This talk concerns subsonic-sonic potential flows in two dimensional nozzles, which are governed by nonlinear degenerate elliptic equations. For finitely long symmetric nozzles, it is shown that there exists a unique Lipschitz continuous subsonic-sonic flow, and the location of sonic points is classified completely.

On the Cahn-Hilliard equation with dynamic boundary condition and singular potential

吴昊(复旦大学)

We report some recent progresses on the Cahn-Hilliard equation with dynamic boundary conditions, which accounts for nontrivial short-range interactions of the binary mixture near the boundary. When the potentials take the form of physically relevant singular type, we show the well-posedness and long-time behavior of the initial boundary value problem.

Global well-posedness to the 2D Cauchy problem of nonhomogeneous heat conducting Navier-Stokes and magnetohydrodynamic equations with vacuum at infinity

钟新(西南大学)

In this talk, we investigate the 2D Cauchy problem of nonhomogeneous heat conducting magnetohydrodynamic equations in the whole plane. For the initial density allowing vacuum at infinity, we derive the global existence and uniqueness of strong solutions provided that the initial density and the initial magnetic decay not too slowly at infinity. In particular, the initial data can be arbitrarily large. The method is based on delicate spatial weighted estimates and the structural characteristic of the system under consideration. As a byproduct, we get the global existence of strong solutions to the 2D Cauchy problem for nonhomogeneous heat conducting Navier-Stokes equations with vacuum at infinity.

Global well-posedness and decay estimates for three-dimensional compressible Navier-Stokes-Allen-Cahn system

赵晓朋(东北大学)

We study the small data global well-posedness and time-decay rates of solutions to the Cauchy problem for 3D compressible Navier-Stokes-Allen-Cahn equations via a refined pure energy method. In particular, the optimal decay rates of the higher order spatial derivatives of the solution are obtained, the

negative Sobolev norms is shown to be preserved along time evolution and enhance the decay rates.
