Double Positive Solutions of Fourth-Order Nonlinear Boundary Value Problems

We study boundary value problems for fourth-order ordinary differential equation of the form by imposing growth conditions on f and using a generalization of the multiple fixed point theorem by Leggett-Williams, we show the existence of at least two positive solutions.
