On the Existence of Positive Solutions of Fourth-Order Ordinary Differential Equations

We study the existence of positive rolutioru of the equations with either . We show the existence of at least one positive solution iff is either superlinear or sublinear by a simple application of a Fixed Point Theorem in cones.
