Abstract: We study a damped wave equation with a nonlinear damping in the locally uniform spaces and prove well-posedness and existence of a locally compact attractor. An upper bound on the Kolmogorov's $\varepsilon$-entropy is also established using the method of trajectories.

Keywords:  Damped wave equations, nonlinear damping, unbounded domains, locally compact attractor, Kolmogorov's entropy.
