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 ...

Sehgal–Guseman-Type Fixed Point Theorem in b-Rectangular Metric Spaces

Mathematics, 2021
In this paper, we prove a Sehgal–Guseman-type fixed point theorem in b-rectangular metric spaces which provides a complete solution to an open problem raised by Zoran D. Mitrović (A note on a Banach’s fixed point theorem in b-rectangular metric space and

Canonical Energy is Quantum Fisher Information [PDF]

, 2016
In quantum information theory, Fisher Information is a natural metric on the space of perturbations to a density matrix, defined by calculating the relative entropy with the unperturbed state at quadratic order in perturbations. In gravitational physics,

Sehgal Type Contractions on b-Metric Space [PDF]

Symmetry, 2018
In this paper, we analyze two discontinuous self-mappings that satisfy Sehgal-type inequalities in the setup of complete b-metric space. The main results of the paper cover and extend a few existing results in the corresponding literature. Furthermore, we give some illustrative examples to verify the effectiveness and strength of our derived results ...

Poincar\'e inequalities for mutually singular measures [PDF]

, 2014
Using an inverse system of metric graphs as in: J. Cheeger and B. Kleiner, "Inverse limit spaces satisfying a Poincar\'e inequality", we provide a simple example of a metric space $X$ that admits Poincar\'e inequalities for a continuum of mutually ...

Fuzzy Triple Controlled Metric Spaces and Related Fixed Point Results

Journal of Function Spaces, 2021
In this study, we introduce fuzzy triple controlled metric space that generalizes certain fuzzy metric spaces, like fuzzy rectangular metric space, fuzzy rectangular b-metric space, fuzzy b-metric space, and extended fuzzy b-metric space.

Non-Commutative Instantons and the Information Metric [PDF]

, 2002
By using the so-called Information Metric on the moduli space of an anti-selfdual (ASD) Instanton in a Self-Dual (SD) Non-Commutative background, we investigate the geometry of moduli space.

Concerning Fuzzy b-Metric Spaces †

Mathematics, 2023
In an article published in 2015, Hussain et al. introduced a notion of a fuzzy b-metric space and obtained some fixed point theorems for this kind of space.

Rectangular cone b-metric spaces over Banach algebra and contraction principle

Fixed Point Theory and Applications, 2017
Rectangular cone b-metric spaces over a Banach algebra are introduced as a generalization of metric space and many of its generalizations. Some fixed point theorems are proved in this space and proper examples are provided to establish the validity and ...
