Common fixed points for generalized ψ-contractions in weak non-Archimedean fuzzy metric spaces

open access: yesApplied General Topology, 2019
Fixed point theory in fuzzy metric spaces plays very important role in theory of nonlinear problems in applied science. In this paper, we prove an existence result of common fixed point of four nonlinear mappings satisfying a new type of contractive ...

Metrics Fluctuational Theory

open access: yes, 2002
It is supposed the alternative to Quantum Mechanics Axiomatic. Fluctuational Theory save the Mathematics of Quantum Mechanic without change, naming this Mathematics as Method of Indirect Computation. Fluctuational Theory is delete the axiomatic of Quantum Mechanics and replaces it by the assumption of Gravitational Noise.

From homogeneous metric spaces to Lie groups

open access: yesComptes Rendus. Mathématique
We study homogeneous metric spaces, by which we mean connected, locally compact metric spaces whose isometry group acts transitively.After a review of a number of classical results, we use the Gleason–Iwasawa–Montgomery–Yamabe–Zippin structure theory to ...

Multi-valued mappings on Pompeiu-Hausdorff fuzzy b-metric spaces and a common fixed point result

open access: yesVojnotehnički Glasnik
Introduction/purpose: The study of the theory of fuzzy sets was prompted by the presence of uncertainty as an essential part of real-world problems, leading Zadeh to address the problem of indeterminacy. The notion of fuzzy logic was introduced by Zadeh.

Some Topological Characteristics of q-Rung Orthopair Fuzzy Metric Space

open access: yesAdvances in Fuzzy Systems
This paper introduced a novel concept of q-rung orthopair fuzzy (q-ROF) metric spaces, in connection with the idea of q-ROF sets, which generalizes well-known concepts of fuzzy metric spaces and intuitionistic fuzzy metric spaces.

Constant Distortion Embeddings of Symmetric Diversities

open access: yesAnalysis and Geometry in Metric Spaces, 2016
Diversities are like metric spaces, except that every finite subset, instead of just every pair of points, is assigned a value. Just as there is a theory of minimal distortion embeddings of fiite metric spaces into L1, there is a similar, yet undeveloped,

A METRIC THEORY OF MINIMAL GAPS [PDF]

open access: yesMathematika, 2018
Comment: Version 2: Fixed a small bug pointed out by Niclas Technau in the statement of section 3, and added references to few gaps in sequences of fractional parts suggested by Andrew ...

A Note on tvs-G-Cone Metric Fixed Point Theory

open access: yesJournal of Applied Mathematics, 2012
For a tvs-G-cone metric space (𝑋,𝐺) and for the family 𝒜 of subsets of X, we introduce a new notion of the tvs-ℋ-cone metric ℋ with respect to G, and we get a fixed result for the 𝒞ℬ𝒲-tvs-G-cone-type function in a complete tvs-G-cone metric space (𝒜,ℋ ...

Twisted massive non-compact models

open access: yesJournal of High Energy Physics, 2018
We study interacting massive N = (2, 2) supersymmetric field theories in two dimensions which arise from deforming conformal field theories with a continuous spectrum.

M-theory exotic scalar glueball decays to mesons at finite coupling

open access: yesJournal of High Energy Physics, 2018
Using the pull-back of the perturbed type IIA metric corresponding to the perturbation of [1]’s M-theory uplift of [2]’s UV-complete top-down type IIB holographic dual of large-N thermal QCD, at finite coupling, we obtain the interaction Lagrangian ...
