摘要：

对于具有周期性强迫项的Lotka Volterra型种群竞争周期系统,我们证明了 :如果强迫项为负,则系统至少有两个正周期解

关键词: 竞争种群系统, 正周期解, Poincare影射

Abstract:

In the present paper,we consider the Lotka Volterra type n species competing systems with periodic coeffcients and periodic forced terms.We prove that if the forced terms are negative, the system has at least two positive (componentwise)periodic solutions.

Key words: competing species systems, positive periodic solutions, Poincare mapping
