Estimating Fixed Points via New Iterative Scheme with an Application

Journal of Function Spaces, 2022
In this paper, we introduce a new scheme and prove convergence results for nonexpansive mappings as well as for weak contractions in the frame of Banach spaces. Moreover, we prove analytically and numerically that the proposed scheme converges to a fixed

Some Fixed Point Theorems Via Combination of Weak Contraction and Caristi Contractive Mapping

Annales Mathematicae Silesianae, 2021
In this paper we introduce some new types of contractive mappings by combining Caristi contraction, Ćirić-quasi contraction and weak contraction in the framework of a metric space.

Decrement Operators in Belief Change

, 2019
While research on iterated revision is predominant in the field of iterated belief change, the class of iterated contraction operators received more attention in recent years.

Basic Logic and Quantum Entanglement [PDF]

, 2006
As it is well known, quantum entanglement is one of the most important features of quantum computing, as it leads to massive quantum parallelism, hence to exponential computational speed-up.

Fixed point theorems for nonlinear contractive mappings in ordered b-metric space with auxiliary function

BMC Research Notes, 2020
Objectives In this paper we present some fixed point theorems for self mappings satisfying generalized $$(\phi , \psi )$$ ( ϕ , ψ ) -weak contraction condition in partially ordered complete b-metric spaces.

Fixed point results for weak contractions in partially ordered b-metric space

BMC Research Notes, 2021
Objectives We explore the existence of a fixed point as well as the uniqueness of a mapping in an ordered b-metric space using a generalized $$({\check{\psi }}, \hat{\eta })$$ ( ψ ˇ , η ^ ) -weak contraction.

Fixed point results for β - F-weak contraction mappings in complete S-metric spaces

Vojnotehnički Glasnik
Introduction/purpose: This paper introduces the concept of β - F-weak contraction by using the concepts of F-weak contraction and a - pscontraction. Methods: The use of the β - F-weak contraction proves some fixed points theorems in the framework of S ...

Fixed Point Theorems for Set-Valued Mappings on TVS-Cone Metric Spaces

, 2015
In the context of tvs-cone metric spaces, we prove a Bishop-Phelps and a Caristi's type theorem. These results allow us to prove a fixed point theorem for $(\delta, L)$-weak contraction according to a pseudo Hausdorff metric defined by means of a cone ...
