一类具有4∶-5共振奇点的复三次Lotka-Volterra系统的可积性条件
Integrability Conditions for a Class of Complex Cubic Lotka-Volterra Systems with a 4 ∶-5 Resonant Singular Point
摘要
Abstract
For a class of complex cubic Lotka-Volterra systems with a 4 ∶-5 resonant singular point, the sufficient conditions for integrability are obtained through the computation of the first eight generalized singular point values.All these conditions are verified by constructing integrating factors or formal first in-tegrals.关键词
