Abstract:
For a certain class of second-order hyperbolic systems, a mixed problem with Dirichlet and Poincaré boundary conditions is studied. In the linear case, an explicit representation of a soultion of this problem is given and questions related to its uniqueness and existence are studied depending on the character of nonlinearities in the system.
Keywords:semilinear hyperbolic system, mixed problem, a priori estimate, Laplace invariants.
