We study mixed hyperbolic systems with dynamic and Wentzell boundary conditions. The boundary condition contains a tangential operator which is strongly elliptic on the boundary. We prove results of generation of strongly continuous groups and well-posedness.

具有动态和Wentzell边界条件的双曲混合问题

我们研究动态和Wentzell边界条件的混合双曲系统。边界条件包含一个切向算子，该算子在边界上是强椭圆形的。我们证明了产生强连续群和适定性的结果。
