%X In this paper, the existence of multiple nontrival positive solutions for a class of singular second order three point boundary value problems with sign changing nonlinearities is investigated. Growth conditions are imposed on $f$, which yield the existence of at least three nontrival positive solutions by using the Leggett-Williams fixed point theorem.
