摘要:
We consider the behavior of the positive solutions to a semilinear parabolic system u(t) = Delta u + e(p nu)u(alpha) and nu(t) = Delta nu + u(q)e(beta nu) with null Dirichlet boundary conditions. We prove that the solutions will blow up in finite time and establish the exact blow-up rates under some conditions. (c) 2010 Elsevier Ltd. All rights reserved.
