On Leibniz-Poisson special polynomial identities

open access: yesVestnik Samarskogo Gosudarstvennogo Tehničeskogo Universiteta. Seriâ: Fiziko-Matematičeskie Nauki, 2014
In this paper we study Leibniz-Poisson algebras satisfying polynomial identities. We study Leibniz-Poisson special and Leibniz-Poisson extended special polynomials.

On tractability and congruence distributivity [PDF]

open access: yesLogical Methods in Computer Science, 2007
Constraint languages that arise from finite algebras have recently been the object of study, especially in connection with the Dichotomy Conjecture of Feder and Vardi.

VARIETIES OF REPRESENTATIONS OF GROUPS AND VARIETIES OF ASSOCIATIVE ALGEBRAS [PDF]

open access: yesInternational Journal of Algebra and Computation, 2011
This paper is tightly connected with the book [Varieties of Group Representations. General Theory, Connections and Applications (Zinatne, Riga, 1983) (in Russian)]. In the paper we prove new results in the spirit of the above-mentioned book. They are related to dimension subgroups, varieties of representations of groups and varieties of associative ...

Higher-dimensional automorphic lie algebras [PDF]

open access: yes, 2016
The paper presents the complete classification of Automorphic Lie Algebras based on sln(C)sln(C) , where the symmetry group G is finite and acts on sln(C)sln(C) by inner automorphisms, sln(C)sln(C) has no trivial summands, and where the poles are in ...

Interior Algebras and Varieties

open access: yesJournal of Algebra, 1999
The authors consider rings and semigroups with an additional unary operation which mimics the operation of taking the interior of a subset in topological spaces. More precisely, they call a ring or semigroup \(R\) an interior algebra if \(R\) is equipped with a unary operation \(a\mapsto I(a)\) such that \(I(a)I(b)=I(b)I(a)\), \(aI(a)=I(a)\), \(I(I(a))=

The Bottleneck Degree of Algebraic Varieties [PDF]

open access: yesSIAM Journal on Applied Algebra and Geometry, 2020
A bottleneck of a smooth algebraic variety $X \subset \mathbb{C}^n$ is a pair of distinct points $(x,y) \in X$ such that the Euclidean normal spaces at $x$ and $y$ contain the line spanned by $x$ and $y$. The narrowness of bottlenecks is a fundamental complexity measure in the algebraic geometry of data. In this paper we study the number of bottlenecks

Modular Abbott Algebras

open access: yesAxioms
This note adds to the investigation of Abbott algebras in relation to quantum logics (see the references below). We introduce a variety of modular Abbott algebras and show that they are isomorphic to the variety of modular quantum logics.

Varieties of ordered algebras

open access: yesJournal of Computer and System Sciences, 1976
A variety of ordered algebras is a class K of ordered algebras satisfying satisfying a set of inequalities t≤t′. It is shown that a class K of ordered algebras is a variety if K is closed under subalgebras, products, and certain homomorphic images. The process of obtaining a “canonical” ω-completion of an ordered algebra is analyzed and it is shown ...
