摘要: 以分层理论为基础,讨论了不可压、无粘流体的Euler方程的形式可解性,并给出了各类不适定初值问题存在形式解的条件与计算方法。并讨论了超曲面上和超平面上初值问题的适定性并给出了存在不唯一解的例证。Abstract: The solvability of the Euler equations about imcompressible inviscid flow based on the stratification theory is discussed.And the conditions for the existence of formal solutions and the methods are presented for calculating all kinds of ill-posed initial value problems.Two examples are given as the evidence that the initial problems at the hyper surface does not exist any unique solution.
