摘要: 考察粘性等离子体物理中的非等熵可压缩Navier-Stokes-Maxwell方程组.借助非常数平衡解的小性以及对称子技巧,研究了三维全空间上的Cauchy问题.在初值为该平衡解的一个小摄动前提下,证明了该问题存在整体唯一光滑解.Abstract: This paper is concerned with non-isentropic compressible Navier-Stokes-Maxwell systems arising from viscosity plasmas. By using techniques of symmetrizer and the smallness of non-constant steady-state solutions, the global existence of solutions to Cauchy problems with prepared initial data was investigated. It is shown that this problem admits globally smooth solutions near a non-constant steady state.
