半耗散理想Boussinesq方程的高阶正则性与爆破准则

Higher Order Regularity and Blow-up Criterion for Semi-dissipative and Ideal Boussinesq Equations

Utpal Manna, Akash A. Panda

摘要:

本文建立了$\mathbb{R}^n , n = 2,3$中粘性零热扩散Boussinesq方程的$H^s$强解的局部时间存在唯一性.在三维涡量的$BMO$范数下建立了Beale-Kato-Majda型爆破准则。我们进一步证明了非粘性完全理想Boussinesq系统的局部存在性和爆破准则。Kato和Ponce(1988)\cite {KP}和Fenchman et.等人(2014)\cite {Fe}在计算中发挥重要作用。

英文摘要:

In this paper we establish local-in-time existence and uniqueness of strong solutions in $H^s$ for $s > \frac{n}{2}$ to the viscous, zero thermal-diffusive Boussinesq equations in $\mathbb{R}^n , n = 2,3$. Beale-Kato-Majda type blow-up criterion has been established in three-dimensions with respect to the $BMO$-norm of the vorticity. We further prove the local-in-time existence and blow-up criterion for non-viscous and fully ideal Boussinesq systems. Commutator estimates due to Kato and Ponce (1988) \cite {KP} and Fefferman et. al. (2014) \cite {Fe} play important roles in the calculations.
