A Stability Problem for the 3D Magnetohydrodynamic Equations Near Equilibrium
This paper is concerned with a stability problem on perturbations near a physically important steady state solution of the 3D MHD system. We obtain three major results. The first assesses the existence of global solutions with small initial data. Second, we derive the temporal decay estimate of the...
