| Abstract: | The dynamical behavior of the random partly dissipative lattice dynamical systems is discussed in this paper by using random analysis and functional analysis. The unique existence is first proved for the solutions of the random partly dissipative lattice dynamical systems, and a priori estimate is obtained on the solutions. The existence of an absorbing set is then discussed for the systems. An estimate on tails of the solutions is derived when the time is large enough, which ensures the asymptotic compactness of solutions. Finally, the global attractor is proved to exist. |
