具年龄结构与扩散的非合作离散系统

AGE-STRUCTURE AND DISCRETE NON-COOPERATIVE SYSTEM OF DIFFUSION

讨论了多种群具年龄结构的非合作Ebenman离散模型 ,且成年种群能够在两缀块间扩散 .应用不变集原理 ,ω—极限集及Lyapunov函数方法 ,获得了排斥原理 ,即得到系统中优势种群 (或拟优势 )导致其他种群最终走向灭绝的充分条件 .

This paper discusses a multi-species discrete model of Ebenman for the dynamics of reproducting population that consists of noncooperation between juveniles and adults which diffuse between two patches .We obtain exclusion principles by the Lyapunov function methods .$$$$
