Unique Common Fixed Points for Expansive Maps

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2023
In this work, we establish three common fixed point results for expansive maps satisfying implicit relations in metric and dislocated metric spaces. We do this by utilizing recently developed concept of occasionally weakly biased maps of type A.

Compatible mappings and common fixed points [PDF]

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1986
A generalization of the commuting mapping concept is introduced. Properties of this “weakened commutativity” are derived and used to obtain results which generalize a theorem by Park and Bae, a theorem by Hadzic, and others.

Results on common fixed points [PDF]

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2001
We establish common fixed point theorems related with families of self mappings on metric spaces. Our results extend, improve, and unify the results due to Fisher (1977, 1978, 1979, 1981, 1984), Jungck (1988), and Ohta and Nikaido (1994).

Common fixed points under strict conditions [PDF]

open access: yesMathematica Moravica, 2020
In this contribution, three new concepts called reciprocally continuous, strictly subweakly compatible and strictly subreciprocally continuous single and multivalued mappings are given for obtention some common fixed point theorems in a metric space. Our

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

Common Coincidence Points and Common Fixed Points in Fuzzy Semi-Metric Spaces

open access: yesMathematics, 2018
We propose the so-called fuzzy semi-metric space in which the symmetric condition is not assumed to be satisfied. In this case, there are four kinds of triangle inequalities that should be considered.

On Characterizations of Fixed and Common Fixed Points

open access: yesJournal of Mathematical Analysis and Applications, 1998
The authors introduce the concept of \(L\)-mapping which is equivalent to the concept of \(C\)-mapping introduced by \textit{S. Zhang} [Proc. Am. Math. Soc. 97, 343-346 (1986; Zbl 0593.54045)] and establish criteria for the existence of fixed points of \(L\)-mappings.

Common Fixed Points in Modular Spaces

open access: yesIbn Al-Haitham Journal for Pure and Applied Sciences, 2018
     In this paper,there are   new considerations about the dual of a modular spaces and weak convergence. Two common fixed point theorems for a -non-expansive mapping defined on a star-shaped weakly compact subset are proved,  Here the conditions of ...
