可压缩Navier-Stokes- Maxwell equations外流问题解的大时间性态

Large-time behavior of solutions to the outflow problem for the compressible Navier-Stokes-Maxwell equations

Huancheng Yao, Changjiang Zhu

摘要:

本文研究了射线$ \mathbb{R}_+ $上通过Lorentz力与Maxwell方程耦合的可压缩非等熵斯托克斯方程组(称为Navier-Stokes-Maxwell方程组)的外流问题的边界层和3-稀疏波组合解的大时间行为。它将电动力学效应纳入双曲抛物方程组的耗散结构中,比简单的可压缩Navier-Stokes方程斯托克斯方程的耗散结构更为复杂。我们证明了这种典型的复合波型是时间渐近稳定的电磁场的复合边界条件下,在一定的小条件和假设的介电常数是有界的。这可以看作是关于非等熵Navier-Stokes-Maxwell方程IBVP的两种不同波型组合的非线性稳定性的第一个结果。

英文摘要:

We investigate the large-time behavior of solutions toward the combination of the boundary layer and 3-rarefaction waves to the outflow problem for the compressible non-isentropic Navier-Stokes equations coupling with the Maxwell equations through the Lorentz force (called the Navier-Stokes-Maxwell equations) on the half line $ \mathbb{R}_+ $. It includes the electrodynamic effects into the dissipative structure of the hyperbolic-parabolic system and turns out to be more complicated than that in the simpler compressible Navier-Stokes equations. We prove that this typical composite wave pattern is time-asymptotically stable with the composite boundary condition of the electromagnetic fields, under some smallness conditions and the assumption that the dielectric constant is bounded. This can be viewed as the first result about the nonlinear stability of the combination of two different wave patterns for the IBVP of the non-isentropic Navier-Stokes-Maxwell equations.
