Convergence of Diffusive BGK Approximations for Nonlinear Strongly Parabolic Systems
No full textWe 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
Convergence of a Relaxation Approximation to a Boundary Value Problem for Conservation Laws
No full textWEAK SOLUTIONS TO A HYDRODYNAMIC MODEL FOR SEMICONDUCTORS AND RELAXATION TO THE DRIFT-DIFFUSION EQUATION
No full textWe investigate the relaxation problem for the hydrodynamic isentropic Euler-Poisson system when the momentum relaxation time tends to zero. Very sharp estimates on the solutions, independent of the relaxation time, are obtained and used to establish compactness
