一类基因选择模型正周期解的存在性

Existence of Positive Periodic Solutions to a Genotype Selection Model

利用Mawhin重合度理论研究了一类基因选择模型的正周期解的存在性,获得了该差分系统存在正周期解的新的充分条件.

This paper, by using Mawhin＇ s Coincidence degree theory studies the existence of a positive periodic solution to the following genotype selection model and obtains a new sufficient condition for the existence of positive periodic solution of the difference model.
