一类种内竞争模型的稳定性曹贤通（郑州纺织工学院，郑州４５０００７）在本文中，我们研究一种按生殖能力不同而分类的种内竞争模型￣［１］这里，Ｊ（ｔ）和Ａ＿ｉ（ｔ）分别表示幼虫和第ｉ成虫群体的数量；ｎ＞０为固有净增长率￣［２］；０＜π≤１为幼虫到成虫的成活...
A diffetence equation model for the intra-specific competition between juveniles and the larger adults is studied.Study has shown that when adult fertility is density dependent there are two fundamental asymptotic states,an equilibrium state in which bith juveniles and adults are present at all times and a cyclic state in which the juvenile and adult genelations alter-nate,for n>1 but near l,here n is the inhetent net teproductive rate,the positive equilibria and the synchronous 2-cycles have opposite stability properties,the equilibtia are stable and the 2-cycies unstable if a<π,while the equilibria are unstable and the 2-cycles stable if a>π.
