Abstract

In this paper, we study the longtime dynamics for the weakly damped wave equation with quintic non-linearity in a bounded smooth domain of R3.\mathbb{R}^3. Based on the Strichartz estimates for the case of bounded domains, we establish the existence of a strong global attractor in the phase space H2(Ω)H01(Ω)×H01(Ω)H^2(\Omega)\cap H^1_0(\Omega)\times H^1_0(\Omega). Moreover, the finite fractal dimension of the attractor is also shown with the help of the quasi-stable estimation.
