摘要:

文章主要讨论一类带有非局部源与边界条件的半线性抛物系统,通过使用上解与下解技术,证明了系统整体解的存在与有限时间爆破的结果, 而且,还得到了解的一致爆破模式.

关键词: 整体存在性, 爆破, 一致爆破模式

Abstract:

In this paper, the authors deals with a semi-linear parabolic system with nonlinear nonlocal sources and nonlocal boundaries. By using super- and sub-solution techniques,  the global existence and finite time blow-up of solution are proved. Moveover, the uniform blow-up profiles of solutions are discussed.

Key words: Global existence, Blow-up, Uniform blow-up profile
