Existence and uniqueness of fixed points for mixed monotone operators with perturbations

open access: yesElectronic Journal of Differential Equations, 2013
In this article, we study a class of mixed monotone operators with perturbations. Using a monotone iterative technique and the properties of cones, we show the existence and uniqueness for fixed points for such operators.

Qualitative Outcomes on Monotone Iterative Technique and Quasilinearization Method on Time Scale

open access: yesAxioms
In this paper, a nonlinear dynamic equation with an initial value problem (IVP) on a time scale is considered. First, applying comparison results with a coupled lower solution (LS) and an upper solution (US), we improved the quasilinearization method (QLM) for the IVP.

Monotone iterative technique for Caratheodory theory of nonlinear functional random integral equations

open access: yesTamkang Journal of Mathematics, 2002
In this paper some random fixed point theorems for the mappings on an ordered Banach space are proved. As applications, the existence of the extremal solutions of some nonlinear functional random integral equations is obtained under certain monotonicity conditions.

Perturbed Iterative Approximation of Solutions for Nonlinear General -Monotone Operator Equations in Banach Spaces

open access: yesJournal of Inequalities and Applications, 2009
We introduce and study a new class of nonlinear general -monotone operator equations with multivalued operator. By using Alber's inequalities, Nalder's results, and the new proximal mapping technique, we construct some new perturbed iterative ...
