本文报道了在真空自由边界框架下由欧拉和引力欧拉-泊松系统控制的膨胀可压缩气体动力学的最新发展。我们讨论扩展仿射解存在于全球的时间。并对1 < γ ≤ 5 3的Euler方程组和γ = 4 3的Euler-Poisson方程组的非仿射光滑解的整体存在性进行了讨论.
We report on a recent development in the dynamics of expanding compressible gases governed by the Euler and the gravitational Euler-Poisson system in the vacuum free boundary framework. We discuss expanding affine solutions that exist globally-in-time. And we explain the methodology of the global existence of expanding smooth non-affine solutions to the Euler system for 1 < γ ≤ 5 3 and the Euler-Poisson system for γ = 4 3 .
