On the nilpotent Leibniz–Poisson algebras

Vestnik Samarskogo Gosudarstvennogo Tehničeskogo Universiteta. Seriâ: Fiziko-Matematičeskie Nauki, 2012
In this article Leibniz and Leibniz–Poisson algebras in terms of correctness of different identities are investigated. We also examine varieties of these algebras. Let $K$ be a base field of characteristics zero.

Merging Intuitionistic and De Morgan Logics

Mathematics
We introduce De Morgan Heyting logic for Heyting algebras with De Morgan negation (DH-algebras). The variety DH of all DH-algebras is congruence distributive. The lattice of all subvarieties of DH is distributive.

Equivalential algebras with conjunction on the regular elements

Annales Universitatis Paedagogicae Cracoviensis: Studia Mathematica, 2021
We introduce the definition of the three-element equivalential algebra R with conjunction on the regular elements. We study the variety generated by R and prove the Representation Theorem.

Green's-Like Relations on Algebras and Varieties

International Journal of Mathematics and Mathematical Sciences, 2008
There are five equivalence relations known as Green's relations definable on any semigroup or monoid, that is, on any algebra with a binary operation which is associative.

C-Ideals of Lie Algebras. [PDF]

, 2009
A subalgebra B of a Lie algebra L is called a c-ideal of L if there is an ideal C of L such that L = B + C and B \cap C \leq B_L, where B_L is the largest ideal of L contained in B.

Invariants of automorphic lie algebras [PDF]

Automorphic Lie Algebras arise in the context of reduction groups introduced in the late 1970s [35] in the field of integrable systems. They are subalgebras of Lie algebras over a ring of rational functions, denied by invariance under the action of a ...

Algebraic Correspondences between Algebraic Varieties

Journal of the Mathematical Society of Japan, 1951
Über dem komplexen Zahlkörper als Konstantenkörper werden zwei vollständige (complete) MannigfaItigkeiten \(U\) und \(V\) betrachtet. Ein Divisor \(X\) von \(U\times V\) wird \glqq Korrespondenz\grqq{} zwischen \(U\) und \(V\) genannt. \(X\) heißt von der Wertigkeit \(0\), wenn er die Form besitzt: \(X = Y_1 \times U\times Y_2 + (\varphi)\), wo \(Y_1\)

Automorphic Lie algebras with dihedral symmetry [PDF]

, 2014
The concept of automorphic Lie algebras arises in the context of reduction groups introduced in the early 1980s in the field of integrable systems.
