Abstract: We gave a monotonicity theorem of second order differential equations under the integral boundary value condition which can be applied to determining the existence of solutions for second order differential equations of right function f(t,x,x′) satisfying Nagumo condition. The main tool used in the proofs is LeraySchauder degree theory.

Key words: integral boundary value condition, existence, monotonicity theorem
