The combined relaxation and non-relativistic approximation of the drift-diffusion model

Jianwei Yang^a,*, Xiaoxia Yang^b

ABSTRACT: In this article, we study the combined relaxation and non-relativistic limit for compressible Euler-Maxwell equations for plasma. For the initial data in equilibrium, the convergences of solutions of compressible Euler-Maxwell equations to the solutions of drift-diffusion model are justified rigorously.
