The Universal Askey-Wilson Algebra [PDF]

open access: yesSymmetry, Integrability and Geometry: Methods and Applications, 2011
In 1992 A. Zhedanov introduced the Askey-Wilson algebra AW=AW(3) and used it to describe the Askey-Wilson polynomials. In this paper we introduce a central extension Δ of AW, obtained from AW by reinterpreting certain parameters as central elements in ...

Quantum groups, Yang–Baxter maps and quasi-determinants

open access: yesNuclear Physics B, 2018
For any quasi-triangular Hopf algebra, there exists the universal R-matrix, which satisfies the Yang–Baxter equation. It is known that the adjoint action of the universal R-matrix on the elements of the tensor square of the algebra constitutes a quantum ...

Automorphisms of the universal enveloping algebra of a finite-dimensional Zinbiel algebra with zero multiplication

open access: yesҚарағанды университетінің хабаршысы. Математика сериясы, 2023
In recent years there has been a great interest in the study of Zinbiel (dual Leibniz) algebras. Let A be Zinbiel algebra over an arbitrary field K and let e1,e2,...,em,... be a linear basis of A. In 2010 A.

Post-Lie algebras in Regularity Structures

open access: yesForum of Mathematics, Sigma, 2023
In this work, we construct the deformed Butcher-Connes-Kreimer Hopf algebra coming from the theory of Regularity Structures as the universal envelope of a post-Lie algebra.

On the Category of EQ-algebras

open access: yesBulletin of the Section of Logic, 2021
In this paper, we studied the category of EQ-algebras and showed that it is complete, but it is not cocomplete, in general. We proved that multiplicatively relative EQ-algebras have coequlizers and we calculated coproduct and pushout in a special case ...

Universal corner symmetry and the orbit method for gravity

open access: yesNuclear Physics B, 2023
A universal symmetry algebra organizing the gravitational phase space has been recently found. It corresponds to the subset of diffeomorphisms that become physical at corners – codimension-2 surfaces supporting Noether charges.

Pseudo-free families and cryptographic primitives

open access: yesJournal of Mathematical Cryptology, 2022
In this article, we study the connections between pseudo-free families of computational Ω\Omega -algebras (in appropriate varieties of Ω\Omega -algebras for suitable finite sets Ω\Omega of finitary operation symbols) and certain standard cryptographic ...

On even spin W ∞ $$ {\mathcal{W}}_{\infty } $$

open access: yesJournal of High Energy Physics, 2020
We study the even spin W ∞ $$ {\mathcal{W}}_{\infty } $$ which is a universal W -algebra for orthosymplectic series of W $$ \mathcal{W} $$ -algebras. We use the results of Fateev and Lukyanov to embed the algebra into W 1 + ∞ $$ {\mathcal{W}}_{1+\infty }

On the Relationship between Jordan Algebras and Their Universal Enveloping Algebras

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2020
The relationship between JW-algebras (resp. JC-algebras) and their universal enveloping von Neumann algebras (resp. C∗-algebras) can be described as significant and influential. Examples of numerous relationships have been established.

The Reticulation of a Universal Algebra [PDF]

open access: yesScientific Annals of Computer Science, 2018
The reticulation of an algebra A is a bounded distributive lattice L(A) whose prime spectrum of filters or ideals is homeomorphic to the prime spectrum of congruences of A, endowed with the Stone topologies.
