We prove constructively existence and uniqueness of a continuous fixed-point for a class of decreasing and pointwise nzonotonically continuous (nonlinear) operators in spaces of (vector-valued) functions, without resorting to complete continuity. As an application, we rediscuss and improve recent results for a class of perturbed nonlinear integral equations.

Abstract

We prove constructively existence and uniqueness of a continuous fixed-point for a class of decreasing and pointwise nzonotonically continuous (nonlinear) operators in spaces of (vector-valued) functions, without resorting to complete continuity. As an application, we rediscuss and improve recent results for a class of perturbed nonlinear integral equations.
