| Abstract: | This paper is concerned with the second-order multipoint boundary value problems with delay.By using a generalization of Leggett-Williams fixed-point theorem due to Avery and Peterson,we provide sufficient conditions for the existence of at least three positive solutions to the boundary value problems. |
