一类退化反应扩散系统解的整体存在与有限爆破

Global Existence and Finite Blow up on the Solutions of A Kind of Degenerate Reaction-diffusion System

通过构造一类退化反应扩散系统的上下解,给出了该系统在临界条件下,解的整体存在及在有限时间内爆破的充分条件。

By the way of upper and lower solution method , the sufficient condition on the solutions was given for the global existence and finite blow up of a kind of degenerate reaction - diffusion system.
