Boundary Value Problems 2010, 2010:106962  doi:10.1155/2010/106962

Published: 28 July 2010


We investigate the following fourth-order four-point nonhomogeneous Sturm-Liouville boundary value problem: , , , where and are nonnegative parameters. Some sufficient conditions are given for the existence and uniqueness of a positive solution. The dependence of the solution on the parameters is also studied.
