Uniform persistence and existence of strictly positive solutions in nonautonomous Lotka-Volterra competitive systems with delays
In this paper, we establish some new sufficient conditions for uniform persistence and existence of strictly positive solutions of the general nonautonomous N-species competitive Lotka-Volterra systems with delays. These results are different to those in [1-4]. (C) 1999 Elsevier Science Ltd. All rights reserved.
