摘要
研究了具有任意Dirichlet边界值的一类含有梯度与非常系数项的非线性抛物方程,证明了方程解的爆破,以及初始值足够大时解的梯度也爆破.
In this paper, a class of nonlinear parabolic equations with gradient dependent and with nonconstant coefficient are studied. The existence of solutions which blow-up at a finite time are proved. At the same time, it is also proved that the gradient blow-up occurs for suitably large initial data.
