Abstract

Abstract In this paper, we consider the following nonlinear boundary value problem: ( φ ( u ( t ) ) ) + a ( t ) f ( u ( t ) ) = 0 , 0 < t < 1 , u ( 0 ) = i = 1 m 2 α i u ( ξ i ) , u ( 1 ) = 0 , where φ : R R is an increasing homeomorphism and positive homomorphism with φ ( 0 ) = 0 . By using a fixed-point theorem on partially ordered sets, we obtain sufficient conditions for the existence and uniqueness of positive and nondecreasing solutions to the above boundary value problem.
