Pullback attractors for two dimensional magnetohydrodynamic equations with delays in sub-linear operators

The paper concerns the asymptotic dynamics for two dimensional magnetohydrodynamic (2D MHD) equations with delays in sub-linear operators. First, we propose some appropriate assumptions of delays and establish the well-posedness of weak solutions. Then, the process U(·, ·) generated by the weak solutions is constructed in MH2(=H×LH2). Finally, we prove the existence of a compact pullback attractor.
