L-Fuzzy Invariant Metric Space

Communications in Advanced Mathematical Sciences, 2018
In this paper, we define L-fuzzy invariant metric space, and generalize some well known results in metric and fuzzy metric space including Uniform continuity theorem and Ascoli-Arzela theorem.

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.

Compact manifolds with computable boundaries [PDF]

, 2013
We investigate conditions under which a co-computably enumerable closed set in a computable metric space is computable and prove that in each locally computable computable metric space each co-computably enumerable compact manifold with computable ...

Rectangular b-metric space and contraction principles

, 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

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.

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

, 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 ...

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

Computer 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.

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,

No Fuss Distance Metric Learning Using Proxies [PDF]

IEEE International Conference on Computer Vision, 2017
We address the problem of distance metric learning (DML), defined as learning a distance consistent with a notion of semantic similarity. Traditionally, for this problem supervision is expressed in the form of sets of points that follow an ordinal ...
