Abstract: This paper deals with the study of boundary value problem for second order ordinary differential equations with integral boundary conditions.By means of fixed-point theorems,some sufficient conditions are obtained to guarantee the uniqueness of positive solution and existence of at least three positive solutions of the boundary value problems.

Key words: ordinary differential equations, integral boundary conditions, positive solutions, fixed-point theorem
