【摘要】 在本文中，作者考察了n种群Lotak-Volterra周期捕食-竟争系统，用比较定理、Brouwer不定点定理和V函数方法证明了正解的最终有界性、正周期解的存在性、正周期解的全局吸引性及唯一性．更多还原

【Abstract】 In this paper，the authors consider an n-species Lotka-Volterra periodic preycompetition systems．Using a comparison method，Brouwer fixed point theorem and V-function method，we discuss the ultimate boundedness of positive solutions，the existence and global attrac-tivity of a positive periodic solution.更多还原
