Multiple Positive Periodic Solutions for Functional Differential Equations with Impulses and a Parameter
We apply the Krasnoselskii fixed-point theorem to investigate the existence of multiple positive periodic solutions for a class of impulsive functional differential equations with a parameter; some verifiable sufficient results are established easily. In particular, our results extend and improve so...
