| Abstract: | In this paper,under suitable hypotheses on the operator and nonlinear term we study the initial boundary value problem for the nonlinear wave equation of higher order with damping and source terms.Using the Holder inequality,Young inequality and Gronwall inequality,by the classical Galerkin's method we establish the global existence of solution via verifying the compactness. |
