Title: Persistence of spreading speed for the delayed Fisher equation
  
Author: Shuxia Pan (Lanzhou Univ. of Technology, Gansu, China)

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.
