Novel results for separate families of fuzzy-dominated mappings satisfying advanced locally contractions in b-multiplicative metric spaces with applications

Journal of Inequalities and Applications
The objective of this research is to present new fixed point theorems for two separate families of fuzzy-dominated mappings. These mappings must satisfy a unique locally contraction in a complete b-multiplicative metric space.

An algebraic characterization of complete inner product spaces

International Journal of Mathematics and Mathematical Sciences, 1986
We present a characterization of complete inner product spaces using en involution on the set of all bounded linear operators on a Banach space. As a metric conditions we impose a “multiplicative” property of the norm for hermitain operators.

Multiplicative Systems on Ultra-Metric Spaces [PDF]

, 2010
AMS Subj. Classification: MSC2010: 42C10, 43A50, 43A75 We perform analysis of certain aspects of approximation in multiplicative systems that appear as duals of ultrametric structures, e.g. in cases of local fields, totally disconnected Abelian groups satisfying the second axiom of countability or more general ultrametric spaces that do not necessarily ...

Admitting center maps on multiplicative metric space

Journal of Algebraic Systems, 2020
Summary: 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 admitting center maps and we prove some useful theorems.

FPT-Algorithms for computing Gromov-Hausdorff and interleaving distances between trees

Journal of Computational Geometry, 2022
The Gromov-Hausdorff distance is a natural way to measure the distortion between two metric spaces. However, there has been only limited algorithmic development to compute or approximate this distance. We focus on computing the Gromov-Hausdorff distance

Fixed-point theorems of F ⋆ − ( ψ , ϕ ) ${F}^{\star}- ( \psi,\phi )$ integral-type contractive conditions on 1 E $1_{E}$ -complete multiplicative partial cone metric spaces over Banach algebras and applications

Journal of Inequalities and Applications, 2023
In this paper, we introduce some user-friendly versions of integral-type fixed-point results and give some modifications of the classical Banach contraction principle by constructing a special type of contractive restrictions of integral forms for weak ...
