Abstract:

In this paper, we prove a blow-up criterion of strong solutions to the 3-D vis-cous and non-resistive magnetohydrodynamic equations for compressible heat-conducting flows with initial vacuum. This blow-up criterion depends only on the gradient of velocity and the temperature, which is similar to the one for compressible Navier-Stokes equations.

Key words: compressible magnetohydrodynamics, blow-up criterion, vacuum, zero resis-tivity, heat-conducting flows
