Saraswathi Devi (Andhra Univ., Visakhapatnam, India) Kapula R. Prasad (Andhra Univ., Visakhapatnam, India) Abstract: In this article we establish the existence of at least three positive solutions for 3n-th order three-point boundary value problem by using five functional fixed point theorem. We also establish the existence of at least 2m-1 positive solutions of the problem for arbitrary positive integer m. Submitted June 23, 2010. Published December 17, 2010.
