摘要:

The aim of this paper is to prove the well-posedness (existence and uniqueness) of the Lp entropy solution to the homogeneous Dirichlet problems for the anisotropic degenerate parabolic-hyperbolic equations with Lp initial value. We use the device of doubling variables and some technical analysis to prove the uniqueness result. Moreover we can prove that the Lp entropy solution can be obtained as the limit of solutions of the corresponding regularized equations of nondegenerate parabolic type.

关键词: degenerate parabolic-hyperbolic equation, Lp entropy solution, device of doubling variables, vanishing viscosity method
