摘要：
The paper investigates the existence of global attractor for a strongly damped wave equation with fully supercritical nonlinearities: u(tt) - Delta u - Delta u(t) + h(u(t)) + g(u) = f (x). In the case when the nonlinearities h(u(t)) and g(u) are of fully supercritical growth, which leads to that the weak solutions of the equation lose their uniqueness, by introducing the notion of limit solutions and using the theory on the attractor of the generalized semiflow, we establish the existence of global attractor for the subclass of limit solutions of the equation in natural energy space in the sense of strong topology.
