Positive solutions of BVPs on the half-line involving functional BCs
We study the existence of positive solutions on the half-line of a second
order ordinary differential equation subject to functional boundary conditions.
Our approach relies on a combination between the fixed point index for
operators on compact intervals, a fixed point result for operators on
noncompact sets, and some comparison results for principal and nonprincipal
solutions of suitable auxiliary linear equations.Comment: 13 page
