We establish new results on the existence of positive solutions for some multi-point boundary value problems at resonance. Our results are based on a recent Leggett-Williams norm-type theorem due to O'Regan and Zima. We also derive a new result for a three-point problem, previously studied by several authors.

Abstract
We establish new results on the existence of positive solutions for some multi-point boundary value problems at resonance. Our results are based on a recent Leggett-Williams norm-type theorem due to O'Regan and Zima. We also derive a new result for a three-point problem, previously studied by several authors.File in questo prodotto:
