Uniform attractors for 3D MHD equations with nonlinear damping

The aim of this paper is to investigate the uniform attractors for 3D MHD equations with nonlinear damping. Some uniform estimates for strong solutions are established. Furthermore, we prove that 3D damped equations have an $ (\mathbb {V},\mathbb {V}) $ (V,V)-uniform attractor and an $ (\mathbb {V},\mathbf{H}<^>{2}) $ (V,H2)-uniform attractor, and the $ (\mathbb {V},\mathbb {V}) $ (V,V)-uniform attractor is actually the $ (\mathbb {V},\mathbf{H}<^>{2}) $ (V,H2)-uniform attractor.
