| Abstract: | This paper proves that the global attractor of the damped Sine-Gordon equation with homogenous Dirichlet boundary condition reduces to an equilibrium point when and the equilibrium point is exponentially attractive.At the same time, the result is applied to the study of the stabilizability of the system. More general results are given at the end of the paper. |
