摘要：
In this paper, we study the temporal decay of weak solutions to the inhomogeneous heat-conducting magnetohydrodynamic equations. Under appropriate assumptions for external forces, some decay properties for the inhomogeneous heat-conducting systems are obtained. The decay rates coincide with the optimal ones of the classical homogeneous incompressible Navier-Stokes equations.
