Yin, Fu Qi et al., Attractor for lattice system of dissipative Zakharov equation, Acta mathematica Sinica. English series (Print) , 25(2), 2009, pp. 321-342
We consider the asymptotic behavior of solutions of an infinite lattice dynamical system of dissipative Zakharov equation. By introducing new weight inner product and norm in the space and establishing uniform estimate on .Tail End. of solutions, we overcome some difficulties caused by the lack of Sobolev compact embedding under infinite lattice system, and prove the existence of the global attractor; then by using element decomposition and the covering property of a polyhedron in the finite-dimensional space, we obtain an upper bound for the Kolmogorov .-entropy of the global attractor; finally, we present the upper semicontinuity of the global attractor
