Common fixed point theorems for compatible mappings

International Journal of Mathematics and Mathematical Sciences, 1996
By using a compatibility condition due to Jungck we establish some common fixed point theorems for four mappings on complete and compact metric spaces These results also generalize a theorem of Sharma and Sahu.

Common fixed point theorems of contractive-type mappings

International Journal of Mathematics and Mathematical Sciences, 2004
Using the concept of D-metric we prove some common fixed point theorems for generalized contractive mappings on a complete D-metric space. Our results extend, improve, and unify results of Fisher and Ćirić.

New coincidence and common fixed point theorems

Applied General Topology, 2009
In this paper, we obtain some extensions and a generalization of a remarkable fixed point theorem of Proinov. Indeed, we obtain some coincidence and fixed point theorems for asymptotically regular non-self and self-maps without requiring continuity and ...

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

, 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

Fixed 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 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.

Relational Meir-Keeler Contractions and Common Fixed Point Theorems

Journal of Function Spaces, 2022
In this article, we prove some coincidence and common fixed point theorems under the relation-theoretic Meir-Keeler contractions in a metric space endowed with a locally finitely T-transitive binary relation.
