Common Fixed Points Theorems for Self-Mappings in Menger PM-Spaces

Mathematics, 2022
The purpose of this paper is to prove that orbital continuity for a pair of self-mappings is a necessary and sufficient condition for the existence and uniqueness of a common fixed point for these mappings defined on Menger PM-spaces with a nonlinear ...

Multivalued Common Fixed Points Theorem in Complex b-Metric Spaces

Mathematics, 2023
In this paper, we establish a result for the existence of common fixed points for multi-valued mappings, satisfying some contractions for complex-valued b-metric spaces. Finally, we present an example to illustrate and support our results.

General Common Fixed Point Theorems and Applications [PDF]

Journal of Applied Mathematics, 2012
The main result is a common fixed point theorem for a pair of multivalued maps on a complete metric space extending a recent result of Đorić and Lazović (2011) for a multivalued map on a metric space satisfying Ćirić‐Suzuki‐type‐generalized contraction.

Results on common fixed points in S_b-metric spaces [PDF]

E-Journal of Analysis and Applied Mathematics
In this paper, we establish new common fixed point theorems for pairs of weakly compatible mappings within the framework of S_b-metric spaces. By introducing generalized contractive conditions, we demonstrate the existence and uniqueness of common fixed ...

Common fixed points for nonexpansive type fuzzy mappings

International Journal of Mathematics and Mathematical Sciences, 1995
In this paper we define g-nonexpansive and g-nonexpansive type fuzzy mappings and prove common fixed point theorems for sequences of fuzzy mappings satisfying certain conditions on a Banach space. Thus we obtain fixed point theorems for nonexpansive type
