摘要
The Hopf's maximum principles are utilized to deal with the problem on blow-up of the solutions for a class of nonlinear parabolic equations u(t) = del (a (u) del u) + g (x, t) f (u), subject to Neumann boundary conditions. Some nonexistence theorems of global solutions and the bounds of "blow-up time" are obtained.
