From the authors' abstract: ``This paper presents a functional version of Altman's condition as an alternative to the standard inward-outward techniques used in the Krasnoselskii and Leggett-Williams type fixed point theorems. Leggett-Williams type arguments are utilized to minimize the conditions on the boundaries of the functional wedges.'' Moreover, the main fixed point result is applied to prove the existence of a positive solution for a right focal boundary value problem.
