Modified α-ψ-contractive mappings with applications

open access: yes, 2013
The aim of this work is to modify the notions of α-admissible and α-ψ-contractive mappings and establish new fixed point theorems for such mappings in complete metric spaces. Presented theorems provide main results of Karapinar and Samet (Abstr.

On multivalued Suzuki-type θ-contractions and related applications

open access: yesOpen Mathematics, 2020
In this study, we develop the concept of multivalued Suzuki-type θ-contractions via a gauge function and established two new related fixed point theorems on metric spaces. We also discuss an example to validate our results.

Results in Strongly Minihedral Cone and Scalar Weighted Cone Metric Spaces and Applications

open access: yesAnnales Mathematicae Silesianae, 2021
The convergence of sequences and non-unique fixed points are established in ℳ-orbitally complete cone metric spaces over the strongly minihedral cone, and scalar weighted cone assuming the cone to be strongly minihedral.

A Picard-Mann hybrid iterative process

open access: yes, 2013
We introduce a new iterative process which can be seen as a hybrid of Picard and Mann iterative processes. We show that the new process converges faster than all of Picard, Mann and Ishikawa iterative processes in the sense of Berinde (Iterative ...

Existence of positive periodic solutions for first-order nonlinear differential equations with multiple time-varying delays

open access: yesOpen Mathematics, 2022
This study elucidates the sufficient conditions for the first-order nonlinear differential equations with periodic coefficients and time-varying delays to have positive periodic solutions.

The existence and uniqueness of solutions to a functional equation arising in psychological learning theory

open access: yesDemonstratio Mathematica, 2023
The paradigm of choice practice represents the psychological theory of learning in the development of moral judgment. It is concerned with evaluating the implications of several choices and selecting one of them to implement.

Remarks on G-metric spaces and fixed point theorems

open access: yes, 2012
We discuss the introduced concept of G-metric spaces and the fixed point existing results of contractive mappings defined on such spaces. In particular, we show that the most obtained fixed point theorems on such spaces can be deduced immediately from ...

Fixed point and coupled fixed point theorems on b-metric-like spaces

open access: yes, 2013
We first introduce the concept of b-metric-like space which generalizes the notions of partial metric space, metric-like space and b-metric space. Then we establish the existence and uniqueness of fixed points in a b-metric-like space as well as in a ...
