Abstract
By constructing a special cone and using cone compression and expansion fixed point theorem, this paper presents some existence results of positive solutions of singular boundary value problem (BVP, for short) on half-line for a class of second order differential equations. At the same time, the boundedness and unboundedness of positive solutions for BVP are considered also.
