A Hybrid Common Fixed Point Theorem under Certain Recent Properties [PDF]

open access: yesThe Scientific World Journal, 2014
We prove a common fixed point theorem for a hybrid pair of occasionally coincidentally idempotent mappings via common limit range property. Our result improves some results from the existing literature, especially the ones contained in Sintunavarat and ...

A common fixed point theorem for two sequences of self-mappings

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1991
In this paper a common fixed point theorem for two sequences of self-mappings from a complete metric space M to M is proved. Our theorem is a generalization of Hadzic's fixed point theorem[1].

UNIQUE FIXED POINT THEOREMS FOR CONTRACTIVE MAPS TYPE IN T 0 -QUASI-METRIC SPACES [PDF]

open access: yes, 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.

Some Fixed Point Theorems in Fuzzy n-Normed Spaces [PDF]

open access: yes, 2010
The main purpose of this paper is to study the existence of a fixed points in fuzzy n-normed spaces. we proved our main results, a fixed point theorem for a self mapping and a common fixed point theorem for a pair of weakly compatible mappings on fuzzy n-

Common fixed point theorems for two and three mappings

open access: yesFixed Point Theory and Applications, 2020
In this paper, we provide common fixed point theorems for two and three commuting mappings which generalize Darbo’s fixed point theorem. An explicit example is given for illustration.

A Generalized Common Fixed Point Theorem under an Implicit Relation

open access: yesDemonstratio Mathematica, 2015
An extended generalization of recent result of Kikina and Kikina (2011) has been established through the notions of weak compatibility and the property E.A., under an implicit-type relation and restricted orbital completeness of the space.

Common fixed point theorem with w-distance [PDF]

open access: yesMathematical Sciences, 2010
In this paper, we prove the existence of common fixed point for mappings defined on complete metric spaces with $w$-distance $p$ satisfying a general contractive inequality of type integral.

On coincidence theorems for a family of mappings in convex metric spaces

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1987
In this paper, a theorem on common fixed points for a family of mappings defined on convex metric spaces is presented. This theorem is a generalization of the well known fixed point theorem proved by Assad and Kirk. As an application a common fixed point

Fixed-Point Theorems and Common Fixed-Point Theorems on Spaces Equipped With Vector-Valued Metrics [PDF]

open access: yesUkrainian Mathematical Journal, 2013
Several fixed point and common fixed point theorems are obtained for generalized contractions with respect to vector-valued metrics. The classical technique is adapted to the use of vector-valued metrics and matrices having spectral radius less than one.

The Existence of Cone Critical Point and Common Fixed Point with Applications

open access: yesJournal of Applied Mathematics, 2011
We first establish some new critical point theorems for nonlinear dynamical systems in cone metric spaces or usual metric spaces, and then we present some applications to generalizations of Dancš-Hegedüs-Medvegyev's principle and the existence theorem ...
