内容摘要:

We consider an initial-boundary value problem with mixed type boundary conditions for a class of degenerate parabolic-hyperbolic equations. Namely, we consider a Cartesian product domain and split its boundary into two parts. In one of them we impose a Dirichlet boundary condition; in the other, we impose a Neumanncondition.  We apply a normal trace formula for $L^2$-divergence-measurefields to  prove a new strong trace property in the part of the boundary where the Neumann condition is imposed. We establish existence and uniqueness of the entropy solution.
