一类非线性耦合抛物型方程组解的爆破
Blow-up Phenomena for the Coupled Nonlinear Parabolic Equations
【摘要】 文章主要研究带有初边值条件的非线性耦合抛物型方程组解的爆破性质.通过建立微分不等式,给出解在有限时间爆破的充分条件,并得到爆破时刻界的估计.
【Abstract】 We consider the blow-up of the solution to some nonlinear parabolic equations with initial boundary value conditions.By establishing differential inequaties,we know the solution blows up at finite time,and get the bound for the blow-up time.
