CONVERGENCE IN LOTKA-VOLTERRA TYPE DIFFUSIVE DELAY SYSTEMS WITHOUT DOMINATING INSTANTANEOUS NEGATIVE FEEDBACKS

This paper deals with the convergence aspect of diffusive delay Lotka-Volterra systems with infinite delays. It is well known that such a system has a globally asymptotically stable steady state if the negative feedbacks of the intraspecific competitions are dominant and instantaneous. It is shown here that such a globally asymptotically stable steady state continues to exist even if the instantaneous assumption is removed, provided that solutions of the system are eventually uniformly bounded and the delays involved in the intraspecific competitions are small. This work generalises several recent related ones.
