Convergence Results for Contractive Type Set-Valued Mappings

Axioms
In this work, we study an iterative process induced by a contractive type set-valued mapping in a complete metric space and show its convergence, taking into account computational errors.

Meir-Keeler Type Contraction Mappings in $c_0$-triangular Fuzzy Metric Spaces [PDF]

Sahand Communications in Mathematical Analysis, 2018
Proving  fixed point theorem in a fuzzy metric space is not possible for  Meir-Keeler contractive mapping. For this, we introduce the notion of $c_0$-triangular fuzzy metric space.

Several Theorems on Single and Set-Valued Prešić Type Mappings

Mathematics, 2020
In this study, we introduce set-valued Prešić type almost contractive mapping, Prešić type almost F-contractive mapping and set-valued Prešić type almost F-contractive mapping in metric space and prove some fixed point results for these mappings ...

Ordered S-Metric Spaces and Coupled Common Fixed Point Theorems of Integral Type Contraction [PDF]

Mathematics Interdisciplinary Research, 2017
In the present paper, we introduces the notion of integral type contractive mapping with respect to ordered S-metric space and prove some coupled common fixed point results of integral type contractive mapping in ordered S-metric space. Moreover, we give

Effective contraction of Skinning maps

Proceedings of the American Mathematical Society, Series B, 2022
Using elementary hyperbolic geometry, we give an explicit formula for the contraction constant of the skinning map over moduli spaces of relatively acylindrical hyperbolic manifolds.

Revising the Hardy–Rogers–Suzuki-type Z-contractions

Advances in Difference Equations, 2021
The aim of this study is to introduce a new interpolative contractive mapping combining the Hardy–Rogers contractive mapping of Suzuki type and Z $\mathcal{Z}$ -contraction. We investigate the existence of a fixed point of this type of mappings and prove

Suzuki-type fuzzy contractive inequalities in 1-Z-complete fuzzy metric-like spaces with an application

Nonlinear Analysis, 2023
In the piece of this note, we mention various Suzuki-type fuzzy contractive inequalities in 1-Z-complete fuzzy metric-like spaces for uniqueness and existence of a fixed point and prove a few fuzzy fixed point theorems, which are appropriate ...

Optical mapping of contracting hearts [PDF]

The Journal of Physiology, 2023
AbstractOptical mapping is a widely used tool to record and visualize the electrophysiological properties in a variety of myocardial preparations such as Langendorff‐perfused isolated hearts, coronary‐perfused wedge preparations, and cell culture monolayers.

UNIQUE FIXED POINT THEOREMS FOR CONTRACTIVE MAPS TYPE IN T 0 -QUASI-METRIC SPACES [PDF]

, 2014
In [2], Agyingi proved that every generalized contractive mapping defined in a q-spherically complete T 0 -ultra-quasi-metric space has a unique fixed point.

Some PPF Dependent Fixed Point Theorems for Generalized α-F-Contractions in Banach Spaces and Applications

Mathematics, 2018
In this paper, we introduce the concepts of an α -admissible nonself-mapping, an α -F-contractive nonself-mapping, a weak α -F-contractive nonself-mapping, and a generalized α -F-contractive nonself-mapping and ...
