摘要：
This paper is concerned with the nonlinear strongly damped wave equation u(tt) - Delta u(t) - Delta u + f(u(t)) + g(u) - h, with Dirichlet boundary conditions and a time-independent external force h. In the presence of nonlinearities f and g of subcritical and critical growth, respectively, the existence of a global attractor of optimal regularity is established.
