一类修正的磁流体动力学方程随机模型解的存在性和大时间性态

Existence and large time behaviour for a stochastic model of a modified magnetohydrodynamic equations

Paul Andre Razafimandimby, Mamadou Sango

摘要:

本文对描述非牛顿介质在脉动磁场作用下运动的非线性随机偏微分方程进行了数学分析。该系统基本上是通过耦合具有$p$结构的非牛顿流体的动力学方程和Maxwell方程得到的。主要证明了弱鞅解的存在性及其在时间趋于无穷大时的指数衰减性。

英文摘要:

In this paper we initiate the mathematical analysis of a system of nonlinear Stochastic Partial Differential equations describing the motion of turbulent Non-Newtonian media in the presence of fluctuating magnetic field. The system is basically obtained by a coupling of the dynamical equations of a Non-Newtonian fluids having $p$-structure and the Maxwell equations. We mainly show the existence of weak martingale solutions and their exponential decay when time goes to infinity.
