Abstract:

In this paper, we study the long time behavior of the solution of the initial boundary value problem of Boussinesq type equation with damping term:uttu2uutg(u)=f(x). The main result is that the existence of global attractor of the infinite dimensional dynamical system and the existence of the global attractor and the Hausdorff dimension of the attractor in the phase space E=V2×H are proved by the method of semi group decomposition, The abstract ondition of nonlinear term g(u) is verified and given a concrete example.

Key words: Boussinesq type equation, Initial boundary value problem, Infinite dimensional dynamical system, Global attractor, Hausdorff dimension
