二维和三维理想磁Bénard问题的局部存在性和爆破准则

On The Two and Three Dimensional Ideal Magnetic Bénard Problem - Local Existence and Blow-up Criterion

Utpal Manna, Akash A. Panda

摘要:

本文考虑二维和三维理想磁Bénard问题,证明了$H^s$中$s > \frac{n}{2}+1, n = 2,3$强解的局部时间存在唯一性.此外,一个必要条件推导出的奇点发展相对于$BMO$ -规范的涡量和电流,推广Beale-Kato-Majda条件的理想流体力学。

英文摘要:

In this paper, we consider the ideal magnetic Bénard problem in both two and three dimensions and prove local-in-time existence and uniqueness of strong solutions in $H^s$ for $s > \frac{n}{2}+1, n = 2,3$. In addition, a necessary condition is derived for singularity development with respect to the $BMO$-norm of the vorticity and electrical current, generalising the Beale-Kato-Majda condition for ideal hydrodynamics.
