Abstract: In this paper, by constructing a special cone and using the fixed point theorems of cone expansion and cone compression, the existence of two positive solutions to a class of boundary value problem of second order singular differential equations is investigated. The results presented here improve some recent results.

Key words: Cone, Singular boundary value problem, Positive solutions.
