本文研究了粘性依赖于密度的自由边界等熵可压缩平面磁流体力学方程。确切地说,当粘性系数λ(ρ与ρθ成正比,且θ> 为0,其中ρ为密度时,我们通过推导一些新的先验估计,在对初始数据的某些假设下证明了整体解的存在性。
In this paper, we study the isentropic compressible planar magnetohydrodynamic equations with viscosity depending on density and with free boundaries. Precisely, when the viscosity coefficientλ(ρ) is proportional toρθwithθ> 0, whereρis the density, we establish the existence of global solutions under certain assumptions on the initial data by deriving some new a priori estimates.
