Convergence of Diffusive BGK Approximations for Nonlinear Strongly Parabolic Systems

Corrado Lattanzio and Roberto Natalini

Abstract: We study a class of BGK approximations of parabolic systems in one space dimension. We prove stability and existence of global solutions for this model. Moreover, under certain conditions, we prove a rigorous result of convergence toward the formal limit, by using compensated compactness techniques.
