Boundary Value Problems and Free Boundary Problems for Quasilinear Hyperbolic-Parabolic Coupled Systems

摘要

In many applications one meets systems of differential equations which consist of first-order hyperbolic and second-order parabolic subsystems which are nonlinearly coupled. These arise, for instance, in the modeling of motion of a compressible, viscous heat conducting fluid, in radiation hydrodynamics, and in the theory of motion of viscoelastic materials. The relevant equations are presented. The results of this work are local time existence and uniqueness theorems for initial-boundary value problems, including cases with free boundaries, for such systems. The results given are for the case of one space dimension. The methods used involve introducing appropriate variables, the method of iteration, a priori estimation and fixed point theorems.
