TIME PERIODIC SOLUTION TO THE COMPRESSIBLE NAVIER-STOKES EQUATIONS IN A PERIODIC DOMAIN
收藏 引用
Acta Mathematica Scientia 2016年 第4期36卷 1015-1029页
作者: 金春花 杨彤 School of Mathematical Sciences South China Normal University Department of Mathematics City University of Hong Kong
This article is concerned with the time periodic solution to the isentropic compressible Navier-Stokes equations in a periodic domain. Using an approach of parabolic regularization, we first obtain the existence of th... 详细信息
