Persistence of spreading speed for the delayed Fisher equation

Shuxia Pan

Abstract:
This article concerns the long time behavior of the delayed Fisher equation without quasimonotonicity. When the time delay is small and the instantaneous self-limitation effect exists, it is proved that the spreading speed is the same as that of the classical Fisher equation.
