摘要：
Recently, Li-Fu-Wang (Li et al., 2022) established the optimal temporal decay rates of solutions near the equilibrium state to the 3D compressible magnetohydrodynamic system with nonlinear damping alpha|u|(beta-1)u for beta >= 3. In this paper, we further extend Li-Fu-Wang's result to the case beta > 1 by finer energy estimates.
