Abstract:

We study the large-time behavior toward viscous shock waves to the Cauchy problem of the one-dimensional compressible isentropic Navier-Stokes equations with density-dependent viscosity. The nonlinear stability of the viscous shock waves is shown for certain class of large initial perturbation with integral zero which can allow the initial density to have large oscillation. Our analysis relies upon the technique developed by Kanel' and the continuation argument.

Key words: viscous shock waves, density-dependent viscosity, one-dimensional compressible Navier-Stokes equations, nonlinear stability, large density oscillation
