| Abstract: | In this paper, we study the boundary value problems for the hyperbolic system (E_1) and (E_2). where the definite domain D is connected and bounded by a piecewise smooth closed Jordan curve D. The boundary value problem we have considered for the system (E_i) is (P_i). Some results on the existence and uniquenss of the weak solutions and classical solutions to these problems are obtained. |
