Existence and unboundedness of positive solutions for singular boundary value problems on half-line. (English) Zbl 1036.34027

Here, the author gives some existence results on positive solutions to singiular boundary value problems on the half-line for a class of second-order differential equations. He gives also some sufficient conditions to guarantee the boundedness or unboundedness of solutions.
The method used is a generalization of a fixed-point theorem in a special cone.
