Abstract

This paper is concerned with the time-asymptotically nonlinear stability of contact discontinuity to the Cauchy problem of a one-dimensional viscous radiative and reactive gas with large initial perturbation. Our main idea is to use the smallness of the strength of the contact discontinuity to control the possible growth of its solutions induced by the nonlinearity of the system and interactions between the solutions and the contact discontinuity. The key point in our analysis is to obtain the uniform positive lower and upper bounds on the specific volume and the absolute temperature.
