摘要
本文考虑Lotka-Volterra生态系统x=diag(x)(a+Ax)的耗散性。当系统为食饵-捕食者型时给出了判定耗散性的图论方法,并用所给方法详细讨论了4物种Lotka-Volterra系统.
In this paper we consider the dissipativity of the Lotka-Volterra ecological system x=diag(x)(a+Ax). When the system is of prey-predator type we give a graph theory method for determining the dissipativity of the system. Using the method stated we discuss in detail the Lotka-Volterra system of four species.
