摘要
This paper deals with the blow-up of solutions to some nonlinear divergence form parabolic equations with nonlinear boundary conditions. We obtain a lower bound for the blow-up time of solutions in a bounded domain Omega subset of R-n, n >= 3. (C) 2013 Academie des sciences. Published by Elsevier Masson SAS. All rights reserved.
