摘要

We study the magnetic Bénard system in two and three-dimensions. Firstly, we obtain a blow-up criterion of smooth solutions to the magnetic Bénard system without zero magnetic diffusion and thermal diffusivity in R2. Secondly, we derive a blow-up criterion of smooth solutions to the magnetic Bénard system without dissipation in Rn(n=2,3), and in what follows, we improve this result.
