Closed algebras for higher rank, non-Abelian tensor gauge fields

open access: yesNuclear Physics B, 2021
A systematic method is presented for the construction and classification of algebras of gauge transformations for arbitrary high rank tensor gauge fields.

Inductive constructions for Lie bialgebras and Hopf algebras [PDF]

open access: yes, 2006
In recent years, two generalisations of the theory of Lie algebras have become prominent, namely the "semi-classical" theory of Lie bialgebras and the "quantum" theory of Hopf algebras, including the quantized enveloping algebras.

Weakly Idempotent Lattices and Bilattices, Non-Idempotent Plonka Functions

open access: yesDemonstratio Mathematica, 2015
In this paper, we study weakly idempotent lattices with an additional interlaced operation. We characterize interlacity of a weakly idempotent semilattice operation, using the concept of hyperidentity and prove that a weakly idempotent bilattice with an ...

Varieties of complex algebras

open access: yesAnnals of Pure and Applied Logic, 1989
Any \(n+1\)-ary relation R on a set X induces the n-ary operation \(f_ R\) on the set \({\mathcal P}(X)\) of subsets of X defined by \[ f_ R(X_ 1,...,X_ n)=\{y| \exists x_ 1...x_ n(R(x_ 1,...,x_ n,y)\wedge x_ 1\in X_ 1\wedge...\wedge x_ n\in X_ n)\}.

THE VARIETY OF COSET RELATION ALGEBRAS [PDF]

open access: yesThe Journal of Symbolic Logic, 2018
AbstractGivant [6] generalized the notion of an atomic pair-dense relation algebra from Maddux [13] by defining the notion of a measurable relation algebra, that is to say, a relation algebra in which the identity element is a sum of atoms that can be measured in the sense that the “size” of each such atom can be defined in an intuitive and reasonable ...

Golod-Shafarevich algebras, free subalgebras and Noetherian images [PDF]

open access: yes, 2012
It is shown that Golod–Shafarevich algebras of a reduced number of defining relations contain noncommutative free subalgebras in two generators, and that these algebras can be homomorphically mapped onto prime, Noetherian algebras with linear growth.

Many-valued coalgebraic logic over semi-primal varieties [PDF]

open access: yesLogical Methods in Computer Science
We study many-valued coalgebraic logics with semi-primal algebras of truth-degrees. We provide a systematic way to lift endofunctors defined on the variety of Boolean algebras to endofunctors on the variety generated by a semi-primal algebra.

Jordan Algebras Over Algebraic Varieties [PDF]

open access: yesCommunications in Algebra, 2010
We construct Jordan algebras over a locally ringed space using generalizations of the Tits process and the first Tits construction by Achhammer. Some general results on the structure of these algebras are obtained. Examples of Albert algebras over a Brauer-Severi variety with associated central simple algebra of degree 3 are given.

Classification of Four-Dimensional Complex Poisson Algebras

open access: yesAxioms
This paper provides a complete classification of four-dimensional complex Poisson algebras, extending previous work on lower-dimensional cases. We develop a systematic approach that combines the classification of four-dimensional complex commutative ...
