Positive solutions of singular boundary value problem of negative exponent Emden—Fowler equation

This paper investigates the existence of positive solutions of a singular boundary value problem with negative exponent similar to standard Emden-Fowler equation. A necessary and sufficient condition for the existence of C0, 1] positive solutions as well as C¹0, 1] positive solutions is given by means of the method of lower and upper solutions with the Schauder fixed point theorem.
