摘要

本文讨论带Dirichlet边界条件的反应扩散方程组ut(x,t)=△u(x,t)+uα(x,t).up(0,t),vt(x,t)=△v(x,t)+uβ(x,t)vq(0,t),研究了该问题正解的爆破性质并给出爆破集及其爆破速率.

Abstract

This paper deals with the blow-up property of positive solution for a reaction diffusion system ut(x,t) =△u(x,t) + vκ(x,t)up(0,t), vt(x,t) =△v(x,t) + uβ(x,t)vq(0,t), with null Dirichlet boundary conditions. The blow up set and blowup rates are obtained.
