Jordan's Inequality: Refinements, Generalizations, Applications and Related Problems [PDF]

open access: yes, 2006
This is an expository article. Some developments on refinements, generalizations, applications of Jordan’s inequality and related problems, including some estimates for three classes of complete elliptic integrals and several proofs of Wilker’s ...

Generalizations of Weighted Trapezoidal Inequality for Mappings of Bounded Variation and their Applications [PDF]

open access: yes, 2003
In this paper, we establish some generalizations of weighted trapezoid inequality for mappings of bounded variation, and give several applications for r − moment, the expectation of a continuous random variable and the Beta ...

Generalizations of the Sommerfield and Schwinger models

open access: yesJournal of High Energy Physics, 2020
The Sommerfield model with a massive vector field coupled to a massless fermion in 1+1 dimensions is an exactly solvable analog of a Bank-Zaks model.

Generalized continued fractions: a unified definition and a Pringsheim-type convergence criterion

open access: yesAdvances in Difference Equations, 2019
In the literature, many generalizations of continued fractions have been introduced, and for each of them, convergence results have been proved. In this paper, we suggest a definition of generalized continued fractions which covers a great variety of ...

Some Properties of Euler’s Function and of the Function τ and Their Generalizations in Algebraic Number Fields

open access: yesMathematics, 2021
In this paper, we find some inequalities which involve Euler’s function, extended Euler’s function, the function τ, and the generalized function τ in algebraic number fields.

Shift symmetries in (anti) de Sitter space

open access: yesJournal of High Energy Physics, 2019
We construct a class of extended shift symmetries for fields of all integer spins in de Sitter (dS) and anti-de Sitter (AdS) space. These generalize the shift symmetry, galileon symmetry, and special galileon symmetry of massless scalars in flat space to

The dark (BPS) side of thermodynamics in Minkowski4

open access: yesJournal of High Energy Physics, 2022
We explore the BPS limit of asymptotically flat black hole thermodynamics, drawing analogies with recent studies of black holes in anti-de Sitter space. Although ultimately motivated by supersymmetry and quantum gravity, the BPS limit is classically well-

Electroweak multi-monopoles

open access: yesNuclear Physics B, 2023
We construct the multi-charge generalizations for the electroweak magnetic monopole solution of Cho and Maison within a wide range of values of the magnetic charge. We use the same ansatz for the axially symmetric fields as the one previously employed to

General Neural Gauge Fields

open access: yesCoRR, 2023
The recent advance of neural fields, such as neural radiance fields, has significantly pushed the boundary of scene representation learning. Aiming to boost the computation efficiency and rendering quality of 3D scenes, a popular line of research maps the 3D coordinate system to another measuring system, e.g., 2D manifolds and hash tables, for modeling

A Contrastive Study of Lexical Semantics in English

open access: yesArmenian Folia Anglistika, 2005
The article presents the initial generalizations of research in the fields of semantics and lexicography which are based on the examination carried out in 1962.
