On Some Generalizations of Commuting Mappings [PDF]

Abstract and Applied Analysis, 2012
It is shown that occasionally JH operators as well as occasionally weakly biased mappings reduce to weakly compatible mappings in the presence of a unique point of coincidence (and a unique common fixed point) of the given maps.

A New Common Fixed Point Theorem for Three Commuting Mappings

Axioms, 2020
In the present paper, we propose a common fixed point theorem for three commuting mappings via a new contractive condition which generalizes fixed point theorems of Darbo, Hajji and Aghajani et al.

Common fixed point theorem for hybrid pairs of r-weakly commuting mappings [PDF]

Surveys in Mathematics and its Applications, 2010
In this paper we established a common fixed point theorem for four mappings f,g (crisp) and S,T (fuzzy) of R-weakly commuting mapping in a metric space.

Compatible mappings and common fixed points (2)

International Journal of Mathematics and Mathematical Sciences, 1988
A common fixed point theorem of S.L. and S.P. Singh is generalized by weakening commutativity hypotheses and by increasing the number of functions involved.

A Note on Common Fixed Point Results in Uniformly Convex Hyperbolic Spaces

Journal of Mathematics, 2013
It is shown that the notion of mappings satisfying condition (K) introduced by Akkasriworn et al. (2012) is weaker than the notion of asymptotically quasi-nonexpansive mappings in the sense of Qihou (2001) and is weaker than the notion of pointwise ...

On common fixed points of weakly commuting mappings and set-valued mappings

International Journal of Mathematics and Mathematical Sciences, 1986
Our main theorem establishes the uniqueness of the common fixed point of two set-valued mappings and of two single-valued mappings defined on a complete metric space, under a contractive condition and a weak commutativity concept.

Some common fixed point theorems in generalized modular metric spaces with applications

Scientific African
In this paper, we extend the notion of weakly commuting mappings results in modular metric spaces to setting of modular ωG-metric spaces and prove the existence of unique common fixed point of three pairs of weakly commuting self-maps in modular ωG ...

Fixed Points of L-Fuzzy Mappings in Ordered b-Metric Spaces

Journal of Function Spaces, 2018
We prove common fixed point theorems for weakly commuting and occasionally coincidentally idempotent L-fuzzy mappings in ordered b-metric spaces. We also obtain common fixed point for pair of mapping satisfying (JCLR) property. An application to integral

Unified common fixed point theorems under weak reciprocal continuity or without continuity

Applied General Topology, 2014
The purpose of this paper is two fold. Firstly, using the notion of weak reciprocal continuity due to Pant et al. Weak reciprocal continuity and fixed point theorems, Ann. Univ. Ferrara Sez. VII Sci. Mat.
