一类生态系统的Abelian积分的定性分析
A Qualitative Analysis of Abelian Integrals of an Ecosystem
【摘要】 利用Abelian积分的等价性原理,把一类生态系统化为Lienard方程,然后利用Hopf分支等定性理论,简便的证明了该系统无环和有唯一极限环的条件.
【Abstract】 The main tools used is equivalent representation of Abelian integrals,the ecosystem is transformed into a Lienard equation,And according to the Hopf bifurcation theory and so on,we simply prove the conditions of no-existence and uniqueness of limit cycles of this system.
