Extinc非自治竞争Lotka- Volterra系统的灭绝性(英文)

Extinction in Nonautonomous Competitive Lotka-Volterra System

研究了几个种群非自治 L otka- Volterra竞争系统 ,给出了竞争的 n个种群中任意 r个持续生存而 n-

In this paper,we considered a nonautonomous competitive Lotka Volterra system composed of \%n\% species. For any positive integer \%r<n\%, we give out the sufficient condition for the persistence for \%r\% species and extinction for the other \%n-r\% species.
