摘要

This paper is concerned with the Fisher-KPP equation with diffusion and non-local delay.Firstly,we establish the global existence and uniform boundedness of solutions to the Cauchy problem.Then,we establish the spreading speed for the solutions with com-pactly supported initial data.Finally,we investigate the long time behavior of solutions by numerical simulations.
