摘要: 本文研究耦合磁场的可压缩Navier-Stokes-Poisson方程组的弱强唯一性问题。证明了当绝热指数γ∈[12/7,6]时，系统的耗散弱解与从相同初值出发的强解完全一致。
Abstract: This paper studies the weak-strong uniqueness problem for the magnetically coupled compressible Navier-Stokes-Poisson system. It is proven that when the adiabatic index γ∈[12/7,6] any dissipative weak solution of the system coincides completely with the strong solution emanating from the same initial data.
