Time-dependent global attractors for the strongly damped wave equations with lower regular forcing term
In this paper, based on a new theoretical framework of
time-dependent global attractors (Conti, Pata and Temam \cite{CPT13}),
we consider the strongly damped wave equations $\varepsilon(t)u_{tt}-\Delta u_{t}-\Delta u+f(u)=g(x)$
and establish the existence of attractors
in $\mathcal{H}_{t}=H_{0}^{1}(\Omega)\times L^{2}(\Omega)$
and $\mathcal{V}_{t}=H_{0}^{1}(\Omega)\times H_{0}^{1}(\Omega)$, respectively.
期刊介绍：
Topological Methods in Nonlinear Analysis (TMNA) publishes research and survey papers on a wide range of nonlinear analysis, giving preference to those that employ topological methods. Papers in topology that are of interest in the treatment of nonlinear problems may also be included.
