Title:Singular limits of solutions to compressible elastic fluids
Seminar:Job Candidate Talk
Speaker:Xianpeng Hu
Abstract Link:http://
Abstract:
The understanding of the importance of small parameters in compressible fluids is a fundamental question. In this talk, the convergence from solutions of compressible viscoelastic fluids to the solution of the incompressible Navier-Stokes equations without external forces is considered for ill-prepared initial data as the Mach number and the elastic coefficient go to zero simultaneously. For the inviscid case in two dimensions, the limit will be Yudovich's solution of incompressible Euler equations. A possible extension to compressible magnetohydrodynamical fluids with zero magnetic diffusivity will also be considered.
