Long-term analysis of strongly damped nonlinear wave equations. (English) Zbl 1230.35019

Summary: We consider the strongly damped nonlinear wave equation

u tt -Δu t -Δu+f(u t )+g(u)=h

with Dirichlet boundary conditions, which serves as a model in the description of thermal evolution within the theory of type III heat conduction. In particular, the nonlinearity f acting on u t is allowed to be nonmonotone and to exhibit a critical growth of polynomial order 5. The main focus is the long-term analysis of the related solution semigroup, which is shown to possess the global attractor in the natural weak energy space.
