| Abstract: | In this paper,we study the existence Of positive solutions of nonlocal boundary-value problem for retarded differentialequations. By applying Krasnoselskii's fixed-point theorem,we provide sufficient conditions for the existence of positive solutions andthe corresponding properties of solutions. |
