退化的反应扩散方程组解的全局存在及其爆破

Global Existence and Blow-up of Solutions for Degenerate Reaction-Diffusion System

利用正则化方法讨论了一类退化方程组初边值问题的古典解的存在性 ,构造特征函数 ,通过上。

In this paper, the initial boundary value problem of the degenerate reaction diffusion systems is studied, the regularization method and upper and lower solutions technique are employed to show the existence of classical solutions. The global existence and blow up are discussed and some sufficient conditions of global and blow up solutions are given.
