Blow-up and global solutions for a class of time fractional nonlinear reaction-diffusion equation with weakly spatial source

This paper investigates the blow-up of solutions for a time fractional nonlinear reaction-diffusion equation with weakly spatial source. We first derive two sufficient conditions under which the solutions may blow up in finite time. Then, we prove the existence of global solution when the initial data are small enough. Moreover, the long time behavior of bounded solutions will be analyzed. (C) 2018 Elsevier Ltd. All rights reserved.
