Quadruple Fixed Point Theorems under Nonlinear Contractive Conditions in Partially Ordered Metric Spaces [PDF]

Journal of Applied Mathematics, 2012
We prove a number of quadruple fixed point theorems under 𝜙-contractive conditions for a mapping 𝐹∶𝑋4→𝑋 in ordered metric spaces. Also, we introduce an example to illustrate the effectiveness of our results.

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.

New PPF Dependent Fixed Point Theorems for Suzuki Type GF-Contractions

Journal of Function Spaces, 2015
We introduce new concepts of an αc-GF-contractive nonself-mapping, a weak αc-GF-contractive nonself-mapping, a generalized αc-GF-contractive nonself-mapping, and Suzuki type GF-contractions and establish the existence of PPF dependent fixed point ...

On (α,φ)-weak Pata contractions

MANAS: Journal of Engineering, 2022
In this paper, we give (α,φ)-weak Pata contractive mapping by using the simulation function and multivalued (α,φ)-weak Pata contractions and establish some fixed point results for such contractions.

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.

P-Contractive Mappings On Metric Spaces [PDF]

, 2018
Altun, Ishak/0000-0002-7967-0554In the present paper, we introduce a new concept of P-contractive mappings on metric spaces. We prove that every ordinary contractive mapping is also P-contractive but the converse may not be true in general. We provide an

Fixed point theorem by using ψ–contraction and (ϕ,φ)–contraction in probabilistic 2–metric spaces

Alexandria Engineering Journal, 2020
This research paper investigates and proves some theorems of the fixed point for self–mapping [T:X→X] under (ϕ,ψ)–contractive mappings and (ϕ,φ)–contractive mappings in Menger probabilistic 2–metric space.

Results on Discontinuity at Fixed Point for a New Class of $F$-Contractive Mappings [PDF]

Sahand Communications in Mathematical Analysis, 2023
The search for contractive definitions which do not compel the mapping to be continuous at fixed points remained an open problem for a long time. Several solutions to this open problem have been obtained in last two decades. The current paper,  we aim to

Best proximity point results for generalization of ̌–̌ proximal contractive mapping in fuzzy banach spaces [PDF]

, 2022
The best proximity point is a generalization of a fixed point that is beneficial when the contraction map is not a self-map. On other hand, best approximation theorems provide an approximate solution to the fixed-point equation Tҳ = ҳ.
