Global strong solutions for viscous radiative gas with degenerate temperature dependent heat conductivity in one-dimensional unbounded domains

摘要

In one-dimensional unbounded domains, we prove the global existence of strong solutions to the compressible Navier-Stokes system for a viscous radiative gas, when the viscosity mu is a constant and the heat conductivity kappa is a power function of the temperature theta according to kappa(theta)=kappatheta beta, with beta >= 0 and kappa
