微极方程的部分适当解及其正则性

Partial suitable solutions for the micropolar equations and regularity properties

Diego Chamorro, David Llerena

摘要:

不可压微极系统由两个耦合方程给出:第一个方程给出速度场u的演化,第二个方程给出微旋转场$ω$的演化。本文将考虑这类系统的弱解的正则性问题。为此,我们将引入部分合适解的新概念,它只对速度场u施加特定的行为,并且在压力上的一些经典假设下,我们将获得变量u和$ω$的h{<$}lderian增益。

英文摘要:

The incompressible Micropolar system is given by two coupled equations: the first equation gives the evolution of the velocity field u while the second equation gives the evolution of the microrotation field $ω$. In this article we will consider regularity problems for weak solutions of this system. For this we will introduce the new notion of partial suitable solutions, which imposes a specific behavior for the velocity field u only, and under some classical hypotheses over the pressure, we will obtain a h{ö}lderian gain for both variables u and $ω$.
