摘要

我们的目的是推广Lois-Prados和Precup(2020)的工作，利用krasnoselskii型同伦不动点定理证明具有一般攻击率的非自治Lotka-Volterra动力系统的正周期解在时间尺度上的存在性。

POSITIVE PERIODIC SOLUTIONS OF NONAUTONOMOUS LOTKA–VOLTERRA DYNAMIC SYSTEMS WITH A GENERAL ATTACK RATE ON TIME SCALES

Our purpose is to extend the work of Lois-Prados and Precup (2020) and use the Krasnoselskii-type homotopy fixed-point theorem to prove the existence of positive periodic solutions of nonautonomous Lotka–Volterra dynamic systems with a general attack rate on time scales.
