Nil Algebras with Nonradical Tensor Square [PDF]

Proceedings of the American Mathematical Society, 1988
The paper contains some simple observations on the tensor square of algebras. Applied to the well-known Golod examples, they allow us to produce nil algebras with nonradical tensor square.

Nonlinear Jordan Derivable Mappings of Generalized Matrix Algebras by Lie Product Square-Zero Elements

Journal of Mathematics, 2021
The aim of the paper is to give a description of nonlinear Jordan derivable mappings of a certain class of generalized matrix algebras by Lie product square-zero elements.

THE HEISENBERG'S TRIDIMENSIONAL GROUP H3

Pesquimat, 2014
On the basis of [7], we have the necessary theory to study the Heisenberg's group geometry. This paper goal is to carry the whole results to the tridimensional case.

Quasi-polynomials of Capelli. III [PDF]

Известия Саратовского университета. Новая серия: Математика. Механика. Информатика, 2021
In this paper polynomials of Capelli type (double and quasi-polynomials of Capelli) belonging to a free associative algebra $F\{X\cup Y\}$ considering over an arbitrary field $F$ and generated by two disjoint  countable  sets $X, Y ...

On algebras of generalized Latin squares [PDF]

Mathematica Bohemica, 2011
Summary: The main result of this paper is the introduction of the notion of generalized \(R\)-Latin square, which includes as a special case the standard Latin square as well as the magic square, and also the double stochastic matrix. Further, the algebra of all generalized Latin squares over a commutative ring with identity is investigated.

Chiral algebras of two-dimensional SYK models

Journal of High Energy Physics, 2019
We study chiral algebras in the Q ¯ $$ \overline{Q} $$ -cohomology of two dimensional SYK models with extended supersymmetry. In a special limit discovered in [1], we are able to construct explicitly a “vertical” single-particle higher-spin algebra that ...

ON SELBERG-TYPE SQUARE MATRICES INTEGRALS [PDF]

Journal of Algebraic Systems, 2013
In this paper we consider Selberg-type square matrices integrals with focus on Kummer-beta types I & II integrals. For generality of the results for real normed division algebras, the generalized matrix variate Kummer-beta types I & II are defined under ...

PERMANENT AND DOMINANT OF MATRIX OVER INTERVAL MIN-PLUS ALGEBRA

Barekeng
A min-plus algebra is a set , where is the set of all real numbers equipped with two binary operations, namely minimum and addition . Every square matrix in min-plus algebra can always be calculated as a permanent and dominant matrix.

Δ-algebra and scattering amplitudes

Journal of High Energy Physics, 2019
In this paper we study an algebra that naturally combines two familiar operations in scattering amplitudes: computations of volumes of polytopes using triangulations and constructions of canonical forms from products of smaller ones.
