Common Fixed Points for Suzuki-Generalized Nonexpansive Maps

Journal of Applied Mathematics, 2013
A common fixed point theorem for a pair of maps satisfying condition (C) is proved under certain conditions. We extend the well-knownDeMarr's fixed point theorem to the case of noncommuting family of maps satisfying condition (C).

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.

A Common Fixed Point Theorem for Vicinal Mappings on Geodesic Spaces

Axioms
In 2024, Kimura proposed the modified shrinking method without assuming the existence of a common fixed point for a family of nonexpansive mappings defined on a complete geodesic space with a nonpositive upper curvature bound.

Common Fixed-Point Theorems in Modular Function Spaces Endowed with Reflexive Digraph

International Journal of Mathematics and Mathematical Sciences, 2020
The purpose of this work is to extend the Knaster–Tarski fixed-point theorem to the wider field of reflexive digraph. We give also a DeMarr-type common fixed-point theorem in this context.

Common fixed point theorem for noncompatible maps in probabilistic metric space [PDF]

Surveys in Mathematics and its Applications, 2013
In this paper, we prove a common fixed point theorem for noncompatible maps in probabilistic metric space using implicit relation. Our result does not require either the completeness of the space or continuity of the maps.

Common fixed point theorems for compatible and weakly compatible mappings [PDF]

, 2000
Results on common fixed points for pairs of single and multivalued mappings on a complete metric space are examined. Our work establishes a common fixed point theorem for a pair of generalized contraction self-maps and a pair of set-valued ...
