Existence of Periodic Solutions for Nonlinear Neutral Differential Equations with Functional Delay
It used a variant of Krasnoselskii’s fixed point theorem to show the existence of periodic solutions for nonlinear neutral differential equations with functional delay. The results were obtained by generalizing previous results of Dib and Maroun. An example was given to illustrate the results.
