一类食饵种群具有常数存放率的三次Kolmogorov系统的极限环的存在性和唯一性

Existence and uniqueness of limit cycle for a cubic Kolmogorov system with constant rate between predator-and prey delivering

食饵种群具有常数的存放率,构成一类特殊的三次Kolmogorov系统。本文论证该系统满足极限环存在和唯一性条件。

There is a specific kind of cubic Kolmogorov system with a constant rate between the predator and the prey delivering. This paper demonstrates that this system fulfills the existence and uniqueness conditions for a limit cycle.
