Fuzzy n−Controlled Metric Space

open access: yesInternational Journal of Analysis and Applications, 2023
This manuscript consists of the idea of n−controlled metric space in fuzzy set theory to generalize a number of fuzzy metric spaces in the literature, for example, pentagonal, hexagonal, triple, and double controlled metric spaces and many other spaces ...

A note on Gromov-Hausdorff-Prokhorov distance between (locally) compact measure spaces [PDF]

open access: yes, 2012
We present an extension of the Gromov-Hausdorff metric on the set of compact metric spaces: the Gromov-Hausdorff-Prokhorov metric on the set of compact metric spaces endowed with a finite measure. We then extend it to the non-compact case by describing a

Non-Unique Fixed Point Results in Extended B-Metric Space

open access: yes, 2018
In this paper, we investigate the existence of fixed points that are not necessarily unique in the setting of extended b-metric space. We state some examples to illustrate our results.

Fuzzy Triple Controlled Metric Spaces and Related Fixed Point Results

open access: yesJournal 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.

Banach Fixed Point Theorem in Extended bv(s)-Metric Spaces

open access: yesComputer Sciences & Mathematics Forum, 2023
We define the class of extended bv(s)-metric spaces by replacing the real number s≥1 with a strictly increasing continuous function ϕ in the definition of a bv(s)-metric space.

Rectangular b-metric space and contraction principles

open access: yes, 2015
The concept of rectangular b-metric space is introduced as a generalization of metric space, rectangular metric space and b-metric space. An analogue of Banach contraction principle and Kannan's xed point theorem is proved in this space.

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

open access: yesRatio 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.

A $P$-Adic Spectral Triple [PDF]

open access: yes, 2014
We construct a spectral triple for the C$^*$-algebra of continuous functions on the space of $p$-adic integers by using a rooted tree obtained from coarse-grained approximation of the space, and the forward derivative on the tree. Additionally, we verify

Nonlinear contractions involving simulation functions in a metric space with a partial order

open access: yes, 2015
Very recently, Khojasteh, Shukla and Radenović [F. Khojasteh, S. Shukla, S. Radenović, Filomat, 29 (2015), 1189–1194] introduced the notion of Z-contraction, that is, a nonlinear contraction involving a new class of mappings namely simulation functions ...
