Abstract

Consider the delayed periodic logistic equation, N(t)=N(t) [a(t)-b(t)Np(t-σ(t))-c(t)Nq(t−T(t))], which describes the evolution of a single species. The existence of a positive periodic solution is established by using the method of coincidence degree.

Author Keywords: Positive periodic solution; Delayed logistic equation; Coincidence degree
