磁微极流体方程强解的存在性定理和爆破准则

Existence theorem and blow-up criterion of the strong solutions to the Magneto-micropolar fluid equations

Jia Yuan

摘要:

本文研究了$\R^3$中的磁微极流体方程,证明了$s> {3/2}$在$H^s(\R^3)$中具有初值的强解的存在性,并建立了其爆破准则.我们主要利用Littlewood-Paley分解,得到了光滑解$(u,ω,b)$的Beale-Kato-Majda型爆破准则,它只依赖于速度的涡度$\nabla\times u$.

英文摘要:

In this paper we study the magneto-micropolar fluid equations in $\R^3$, prove the existence of the strong solution with initial data in $H^s(\R^3)$ for $s> {3/2}$, and set up its blow-up criterion. The tool we mainly use is Littlewood-Paley decomposition, by which we obtain a Beale-Kato-Majda type blow-up criterion for smooth solution $(u,ω,b)$ which relies on the vorticity of velocity $\nabla\times u$ only.
