摘要：

In this paper we consider a nonlinear heat equation with nonlinearities of variableexponent type. We show that any solution with nontrivial initial datum blows up in finite time. We also give a two-dimension numerical example to illustrate our result. (C) 2014 Elsevier Ltd. All rights reserved.
