Square-central and Artin–Schreier elements in division algebras [PDF]

open access: yesArchiv Der Mathematik, 2015
We study the behavior of square-central elements and Artin-Schreier elements in division algebras of exponent 2 and degree a power of 2. We provide chain lemmas for such elements in division algebras over 2-fields $F$ of cohomological $2$-dimension $\operatorname{cd}_2(F) \leq 2$, and deduce a common slot lemma for tensor products of quaternion ...

Projective bases of division algebras and groups of central type [PDF]

open access: yesIsrael Journal of Mathematics, 2005
The paper under review continues the study, started by the first two authors, of those twisted group algebras over a field \(k\), which are in fact central division algebras. They have proved [see Isr. J. Math. 121, 173-198 (2001; Zbl 0978.16027)] that the groups corresponding to these algebras are nilpotent, and also, have reduced the presentation of ...

Realizing central division algebras [PDF]

open access: yesPacific Journal of Mathematics, 1983
Eine torsionsfreie abelsche Gruppe heißt \(p\)-lokal, falls \(G\) durch alle Primzahlen \(\neq p\) teilbar ist. Ist \(E(G)\) der Endomorphismenring von \(G\), so heißt die Koeffizientenerweiterung \({\mathbb{Q}}\otimes E(G)\) der Quasiendomorphismenring von \(G\). Die Verff.

EUCLIDEAN MINIMA AND CENTRAL DIVISION ALGEBRAS [PDF]

open access: yesInternational Journal of Number Theory, 2009
The notion of Euclidean minimum of a number field is a classical one. In this paper, we generalize it to central division algebras and establish some general results in this new context.

Identities and central polynomials for real graded division algebras [PDF]

open access: yesInternational Journal of Algebra and Computation, 2017
Let [Formula: see text] be a finite dimensional simple real algebra with a division grading by a finite abelian group [Formula: see text]. In this paper, we provide a finite basis for the [Formula: see text]-ideal of graded polynomial identities for [Formula: see text] and a finite basis for the [Formula: see text]-space of graded central polynomials ...

Finite Dimensional Hopf Actions on Central Division Algebras [PDF]

open access: yesInternational Mathematics Research Notices, 2016
Let $\mathbb{k}$ be an algebraically closed field of characteristic zero. Let $D$ be a division algebra of degree $d$ over its center $Z(D)$. Assume that $\mathbb{k}\subset Z(D)$. We show that a finite group $G$ faithfully grades $D$ if and only if $G$ contains a normal abelian subgroup of index dividing $d$.

A note on Clifford algebras and central division algebras with involution [PDF]

open access: yesGlasgow Mathematical Journal, 1985
In this note we consider the question as to which central division algebras occur as the Clifford algebra of a quadratic form over a field. Non-commutative ones other than quaternion division algebras can occur and it is also the case that there are certain central division algebras D which, while not themselves occurring as a Clifford algebra, are ...
