Some fixed point results in fuzzy metric spaces using a control function [PDF]

Surveys in Mathematics and its Applications, 2017
In this paper, we establish the results on existence and uniqueness of fixed point for φ-contractive and generalized C-contractive mapping in the fuzzy metric space in the sense of George and Veeramani.

Fixed Points of Some Asymptotically Regular Multivalued Mappings Satisfying a Kannan-Type Condition

Axioms, 2021
In this paper, we establish some existence of fixed-point results for some asymptotically regular multivalued mappings satisfying Kannan-type contractive condition without assuming compactness of the underlying metric space or continuity of the mapping.

Some new fixed point results in non-Archimedean fuzzy metric spaces

Nonlinear Analysis, 2013
In this paper, we introduce the notions of fuzzy (α, β, ϕ)-contractive mapping, fuzzy α-φ-ψ-contractive mapping and fuzzy α-β-contractive mapping and establish some results of fixed point for this class of mappings in the setting of non-Archimedean fuzzy

Mappings contracting transverse axis of hyperbola

Applied General Topology
In this paper a new contractive type mapping known as mapping contracting transverse axis of hyperbola is introduced. This mapping can reduce the length of transverse axis of a hyperbola.

On Extended Branciari b-Distance Spaces and Applications to Fractional Differential Equations

Journal of Function Spaces, 2021
In this work, we define new α−λ-rational contractive conditions and establish fixed-points results based on aforesaid contractive conditions for a mapping in extended Branciari b-distance spaces. We furnish two examples to justify the work.

On interpolative Hardy-Rogers type cyclic contractions

Applied General Topology
Recently, Karapınar introduced a new Hardy-Rogers type contractive mapping using the concept of interpolation and proved a fixed point theorem in complete metric space. This new type of mapping, called "interpolative Hardy-Rogers type contractive mapping"

Wardowski Type Contractions and the Fixed-Circle Problem on S-Metric Spaces

Journal of Mathematics, 2018
In this paper, we present new fixed-circle theorems for self-mappings on an S-metric space using some Wardowski type contractions, ψ-contractive, and weakly ψ-contractive self-mappings.

Best Proximity Point Results in Fuzzy Normed Spaces

Science and Technology Indonesia, 2023
Fixed point (briefly FP ) theory is a potent tool for resolving several actual problems since many problems may be simplified to the FP problem. The idea of Banach contraction mapping is a foundational theorem in FP theory.

Diametrically Contractive Multivalued Mappings [PDF]

Fixed Point Theory and Applications, 2007
AbstractDiametrically contractive mappings on a complete metric space are introduced by V. I. Istratescu. We extend and generalize this idea to multivalued mappings. An easy example shows that our fixed point theorem is more applicable than a former one obtained by H. K. Xu.
