Abstract

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.

具有一般攻击率的非自治lotka-volterra动态系统的正周期解

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。

期刊介绍： Rocky Mountain Journal of Mathematics publishes both research and expository articles in mathematics, and particularly invites well-written survey articles. The Rocky Mountain Journal of Mathematics endeavors to publish significant research papers and substantial expository/survey papers in a broad range of theoretical and applied areas of mathematics. For this reason the editorial board is broadly based and submissions are accepted in most areas of mathematics. In addition, the journal publishes specialized conference proceedings.
