A New Common Fixed Point Theorem for Three Commuting Mappings [PDF]

open access: goldAxioms, 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.

A common fixed point theorem for a commuting family of nonexpansive mappings one of which is multivalued [PDF]

open access: goldFixed Point Theory and Applications, 2011
Bruck [Pac. J. Math. 53, 59-71 1974 Theorem 1] proved that for a nonempty closed convex subset E of a Banach space X, if E is weakly compact or bounded and separable and suppose that E has both (FPP) and (CFPP), then for any commuting family S of ...

Common Fixed Points of Commuting Mappings [PDF]

open access: bronzeProceedings of the American Mathematical Society, 1975
Let X X be a dendroid and S S an abelian semigroup of continuous monotone self-mappings of X X . A point x ϵ X x\epsilon X is fixed under S S if g ( x ) = x g(x) = x for all

On Some Generalizations of Commuting Mappings [PDF]

open access: yesAbstract 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.

The symbolDwill be written for the space of indefinitely differentiable functions on the n-dimensional Euclidean spaceRnwhich have compact support andDapos; will denote the space of Schwartz distribution onRn, the topological dual ofD. Except where contrary is explicitly stated, it will be assumed thatD′ is equipped with the strong topology β (D′,D ...

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

open access: goldInternational 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.

Variants of R-weakly commuting mappings and common fixed point theorems in intuitionistic fuzzy metric spaces

open access: greenKuwait Journal of Science, 2014
In this paper, we utilize the notion of common limit range property with variants of  -weakly commuting mappings and obtain some common fixed point theorems in intuitionistic fuzzy metric spaces.

Some Common Fixed Points Theorems of Four Weakly Compatible Mappings in Metric Spaces

open access: yesمجلة بغداد للعلوم, 2021
In this paper, we proved coincidence points theorems for two pairs mappings which are defined on nonempty subset   in metric spaces by using condition (1.1). As application, we established a unique common fixed points theorems for these mappings by using
