摘　　要：研究了Logistic差分方程单个和多重周期正解的存在性理论,利用锥不动点定理证明了解的存在性,并应用本文的理论验证了一些生物数学模型.This paper presents a new existence theory for single and multiple positive periodic solutions to Logistic difference equations. Existence is established using a fixed point theorem in cones. We illustrate our theory be examining several biomathematical models.
