Convergence of Singular Limits for Multi-D Semilinear Hyperbolic Systems to Parabolic Systems

Donatella Donatelli and Pierangelo Marcati

Abstract: In this paper we study the relaxation of multi-D semilinear hyperbolic systems in pseudodifferential form to parabolic systems. The singular limits are studied combining Tartar's and G\'erard's generalized compensated compactness and by using the properties of the pseudodifferential symmetrizers of the system.
