In this paper, we consider a reaction-diffusion system coupled by nonlinear memory. Under appropriate hypotheses, we prove that the solution either exists globally or blows up in finite time. Furthermore, the blow-up rate estimates are obtained.

This article deals with the conditions that ensure the blow-up phenomenon or its absence for solutions of the system ut=△ul+uPlvql and vt=△vm+uP2vq2 with homogeneous Dirichlet boundary conditions. The results depend crucially on the sign of the difference p2ql-(l-pl)(m-q2), the initial data, and the domain Ω.
