摘要: 对于具有某类初值条件的二维可压缩流体Euler方程组,给出了其C1解整体存在的必要条件,从而对[1]、[2]中的"未解决问题"提供了有意义的说明.

Abstract: Under the appropriate assumptions on the initial data, we give a necessary condition on the global existence of C1 solution to two dimensional compressible Euler equation and prove a meaningful result on the "unsolved problem" in references[1],[2],[4] and so on.
