In this talk,we study the stability of contact discontinuities in three dimensional compressible isentropic steady flows.Both of linear and nonlinear stabil
Convexity of shocks is frequently observed in many experimental results and provides better understanding of mathematical problems with the nonlinear wave,t
In this talk,I present recent result on the Prandtl-Meyer reflection impinging onto a solid wedge.This talk is based on collaboration with Gui-Qiang G.Chen(
In a number of recent works,we propose to use partial differential equation models to study the temporal and spatial characteristics of information diffusio
In this talk,we will introduce our recent work on the existence andlinear stability of periodic orbits in the N-body problem.The main tools we useare variat
This paper deals with a competition model with dynamically allocated toxin production in the unstirred chemostat.First,the existence and uniqueness of posit
In this talk,we consider 2D urban crime models describing the spatial heterogeneity of the near-repeat victimization effect and the dispersal strategy of cr
New distributed parallel dense solvers for symmetric positive definite generalized eigenvalue problems were constructed as hybrid ones between the three par
