摘要
In this paper, we investigate a blow-up criterion for compressible magnetohydrodynamic equations. It is shown that if density and velocity satisfy (parallel to rho parallel to(infinity)(L)(0,T;L-infinity) + parallel to u parallel to(C)([0,T];L-3) < infinity), then the strong solutions to isentropic magnetohydrodynamic equations can exist globally over [0,T]. Notably, our analysis accommodates the presence of an initial vacuum.
