We establish the existence of positive solutions of some $m$-point boundary value problems under weaker assumptions than previously employed, in particular we do not require all the parameters occurring in the boundary conditions to be positive. Our results allow more general behaviour for the nonlinear term than being either sub- or super-linear.

Abstract
We establish the existence of positive solutions of some $m$-point boundary value problems under weaker assumptions than previously employed, in particular we do not require all the parameters occurring in the boundary conditions to be positive. Our results allow more general behaviour for the nonlinear term than being either sub- or super-linear.File in questo prodotto:
