Local existence and blow-up criterion for the two and three dimensional ideal magnetic Benard problem

Utpal Manna, Akash Ashirbad Panda

Abstract:
In this article, we consider the ideal magnetic Benard problem in both two and three dimensions and prove the existence and uniqueness of strong local-in-time solutions, in Hs for s > (n/2)+1, n = 2,3. In addition, a necessary condition is derived for singularity development with respect to the BMO-norm of the vorticity and electrical current, generalizing the Beale-Kato-Majda condition for ideal hydrodynamics.
