Existence of positive solutions for Sturm-Liouville boundary value problems on the half-line. (English) Zbl 1104.34020

The authors derive sufficient conditions to guarantee some properties of the positive solutions of the considered Sturm-Liouville problem. It is interesting that the nonlinear term can be sign-changing.
