Boundary Value Problems 2012, 2012:107  doi:10.1186/1687-2770-2012-107

Published: 9 October 2012


This paper deals with the positive solutions of a fourth-order boundary value problem in Banach spaces. By using the fixed-point theorem of strict-set-contractions, some sufficient conditions for the existence of at least one or two positive solutions to a fourth-order boundary value problem in Banach spaces are obtained. An example illustrating the main results is given.
