Positive solutions to a type of multi-point boundary value problem with delay and one-dimensional p-Laplacian

摘要

This paper deals with a type of multi-point boundary value problem with delay and one-dimensional p-Laplacian by using Guo-Krasnosel’skii’ fixed point theorem and generalization of the Leggett–Williams’ fixed point theorem due to Avery and Peterson. We obtain that BVP (1.1) has at least one positive solution or three positive solutions.
