Pullback attractors for 2D MHD equations with delays on unbounded domains
Abstract The aim of the paper is to consider the asymptotic dynamics of weak solutions for 2D MHD equations with delay terms on unbounded domains. First, we propose some appropriate assumptions of the delay terms and establish the existence and uniqueness of weak solutions. Then, the process U ( ⋅ ,...

| Summary: | Abstract The aim of the paper is to consider the asymptotic dynamics of weak solutions for 2D MHD equations with delay terms on unbounded domains. First, we propose some appropriate assumptions of the delay terms and establish the existence and uniqueness of weak solutions. Then, the process U ( ⋅ , ⋅ ) $U(\cdot ,\cdot )$ generated by the weak solutions is constructed. Finally, using the energy method and Arzelà–Ascoli theorem, we can establish the compactness of the process; furthermore, we prove the existence of a compact pullback attractor for the system. |
