| Abstract: | This paper studies the initial boundary value problem for a class of nonlinear wave equations with arbitrary dissipative term.The unique and global existence of weak solution is proved by the use of Galerkin and the potential well method.The asymptotic behavior of the weak solution is studied by the V.Komornik inequality in the state of small initial energy.The results show that some related conclusions are improved and generalized. |
