摘要
This paper deals with the existence of multiple positive periodic solutions to a nonautonomous scalar difference equation subjected to Allee effects. Existence is established using Leggett-Williams multiple fixed point theorem. This result is employed to find the minimum number of positive periodic solutions admitted by a model representing dynamics of a renewable resource that is subjected to Allee effects in a seasonally varying environment.
