Formally Real Involutions on Central Simple Algebras [PDF]

open access: yesCommunications in Algebra, 2008
An involution $#$ on an associative ring $R$ is \textit{formally real} if a sum of nonzero elements of the form $r^# r$ where $r \in R$ is nonzero. Suppose that $R$ is a central simple algebra (i.e. $R=M_n(D)$ for some integer $n$ and central division algebra $D$) and $#$ is an involution on $R$ of the form $r^# = a^{-1} r^\ast a$, where $\ast$ is some

CHARACTERISTIC POLYNOMIALS OF CENTRAL SIMPLE ALGEBRAS

open access: yesTaiwanese Journal of Mathematics, 2013
We characterize characteristic polynomials of elements in a central simple algebra. We also give an account for the theory of rational canonical forms for separable linear transformations over a central division algebra, and a description of separable conjugacy classes of the multiplicative group.

On the corestriction of central simple algebras

open access: yesMathematische Zeitschrift, 1987
This paper provides algebra-theoretic proofs for the following well-known results: (1) if L/K is a separable extension of fields of rank d and C is a central simple algebra over K, then \(cor_{L/K}(C\otimes L)\sim C^{\otimes d}\); (2) if L/K is a finite separable extension of fields and if a, b are non-zero elements of L and K respectively, then for ...

Tame group actions on central simple algebras

open access: yesJournal of Algebra, 2007
We study actions of linear algebraic groups on finite-dimensional central simple algebras. We describe the fixed algebra for a broad class of such actions.

A CHARACTERIZATION OF DERIVATIONS AND AUTOMORPHISMS ON SOME SIMPLE ALGEBRAS

open access: yesUral Mathematical Journal, 2022
In the present paper, we study simple algebras, which do not belong to the well-known classes of algebras (associative algebras, alternative algebras, Lie algebras, Jordan algebras, etc.).

Norms in central simple algebras [PDF]

open access: yesPacific Journal of Mathematics, 2018
Let A be a central simple algebra central over a number field K whose ring of integers is R. An outlier is an element r of R so that: r is a reduced norm of an element of A, but not the norm of an algebraic integer in A. We study properties and distribution of outliers.

Algorithmic complexity of linear nonassociative algebra

open access: yesВестник КазНУ. Серия математика, механика, информатика, 2020
One of the central problems of algebraic complexity theory is the complexity of multiplication in algebras. For this, first, the concept of algebra is defined and the class of algebras under study is fixed.

Higher Derivations and Central Simple Algebras [PDF]

open access: yesNagoya Mathematical Journal, 1968
Let K be a commutative ring, A a K-algebra, and B a K-subalgebra of A. The object of this paper is to prove some results on higher derivations (in the sense of Jacobson [4]) of B into A. In § 1 we introduce a notion of equivalence among higher derivations.
