ADMITTING CENTER MAPS ON MULTIPLICATIVE METRIC SPACE [PDF]

Journal of Algebraic Systems, 2020
‎In this work‎, ‎we investigate admitting center map on multiplicative metric space‎ ‎and establish some fixed point theorems for such maps‎. ‎We modify the Banach contraction principle and‎ ‎the Caristi's fixed point theorem for M-contraction ...

Some fixed points of multivalued maps in multiplicative metric spaces

Heliyon, 2022
In this manuscript, new fixed point theorems for multivalued maps, particularly α−ϕ contractions, in complete multiplicative metric spaces are proved.

Mirror Descent and Exponentiated Gradient Algorithms Using Trace-Form Entropies [PDF]

Entropy
This paper introduces a broad class of Mirror Descent (MD) and Generalized Exponentiated Gradient (GEG) algorithms derived from trace-form entropies defined via deformed logarithms. Leveraging these generalized entropies yields MD and GEG algorithms with

Multiplicative modular metric spaces and some fixed point results

Journal of Inequalities and Applications
This study aims to introduce a novel type of metric, defined as the w-multiplicative modular metric space, which becomes an expanded idea that includes two metric spaces. We present and demonstrate some of this new space’s topological properties. We also

Common fixed point theorem for weakly compatible mappings in Sm metric space

Ratio Mathematica, 2023
In the present paper, at first, we study the structure of the newly Smmetric space, which is a union of S-metric space and multiplicative metric space with new contraction condition.

On Fixed Point Findings for Diverse Contractions in b Dislocated-Multiplicative Metric Spaces

Journal of Mathematics, 2021
In our present research study, we present the idea of b dislocated-multiplicative metric space (abbrev. bd-multiplicative metric space) that is generalization of b-multiplicative metric space and dislocated-multiplicative metric space.

On multiplicative metric spaces: survey [PDF]

Fixed Point Theory and Applications, 2016
AbstractThe purpose of this survey is to prove that the fixed point results for various multiplicative contractions are in fact equivalent to the corresponding fixed point results in (standard) metric spaces. For example, such are recent results established by He et al. (Fixed Point Theory Appl.

Some Theorems on Multiplicative Metric Spaces

Turkish Journal of Computer and Mathematics Education (TURCOMAT), 2023
The aim of this paper is to discuss the fixed point theorems under some contractive conditions in multiplicative spaces. We also give their appropriate examples

A novel study for hybrid pair of multivalued dominated mappings in b-multiplicative metric space with applications

Journal of Inequalities and Applications, 2022
The aim of this paper is to prove some new fixed point results for a pair of multivalued dominated locally contractive mappings in b-multiplicative metric space. Further, fixed point theorems for multigraph-dominated mappings are also established.
