Positive solutions of multipoint ϕ-Laplacian BVPs with first-order derivative dependence

Abstract

This paper concerns existence of positive solutions for a second-order boundary value problem of Sturm–Liouville type associated with a [Formula: see text]-Laplacian operator and posed on a bounded interval. Existence results are obtained by an adapted version of the Krasnosel’skii’s fixed point theorem of cone expansion and compression. Some examples illustrate our results.
