We present sufficient conditions for the existence of positive solutions for some second order boundary value problems at resonance. The boundary conditions that we study are quite general, involve a Stieltjes integral and include, as particular cases, multi-point and integral boundary conditions. Our results are based on a Leggett- Williams norm-type theorem due to O’Regan and Zima. We employ a general abstract approach which allows us to improve and complement recent results in the literature.

Abstract
We present sufficient conditions for the existence of positive solutions for some second order boundary value problems at resonance. The boundary conditions that we study are quite general, involve a Stieltjes integral and include, as particular cases, multi-point and integral boundary conditions. Our results are based on a Leggett- Williams norm-type theorem due to O’Regan and Zima. We employ a general abstract approach which allows us to improve and complement recent results in the literature.File in questo prodotto:
