Fixed point of sum for concave and convex operators with applications
Published online by Cambridge University Press: 17 April 2009
Abstract
In this paper we study fixed points of sums of α-concave and (−α)-convex operators in γ-complete partially ordered linear spaces. As an application we obtain existence and uniqueness theorems for solutions of a certain type of nonlinear integral equation.
