Division algebras of degree 4 and 8 with involution [PDF]
Israel Journal of Mathematics, 1979 We develop necessary and sufficient conditions for central simple algebras to have involutions of the first kind, and to be tensor products of quaternion subalgebras. The theory is then applied to give an example of a division algebra of degree 8 with involution (of the first kind), without quaternion subalgebras, answering an old question of Albert ...

Homogeneous involutions on graded division algebras and their polynomial identities
Journal of Algebra and Its Applications, 2023 In this paper, we describe the so-called homogeneous involution on finite-dimensional graded-division algebra over an algebraically closed field. We also compute their graded polynomial identities with involution. As pointed out by Fonseca and Mello, a homogeneous involution naturally appears when dealing with graded polynomial identities and a ...

On Division Algebras of Degree 3 with Involution
Journal of Algebra, 1996 The authors present a simple proof of the theorem [\textit{A. A. Albert}, Scripta Math. 26, 309-316 (1963; Zbl 0147.28702)] that a division algebra of degree 3 (in characteristic not 3) with an involution \(J\) of the second kind has a maximal subfield which is Galois over the fixed field of \(J\), with the symmetric group of degree 3 as Galois group ...

Division algebras with an anti-automorphism but with no involution [PDF]
advg, 2005 The authors construct interesting examples of division rings having an anti-automorphism but no involutions. The problem stems from projective geometry. It is classical that if \(D\) is a division ring and \(V\) a finite dimensional right \(D\)-vector space of dimension at least 3, then the projective space \(P(V)\) has a duality (resp.

Discriminants of involutions on Henselian division algebras [PDF]
Pacific Journal of Mathematics, 1995 The purpose of this paper is to compute the discriminant of an involution of the first kind on a finite dimensional division algebra over a field with a Henselian valuation of residual characteristic different from 2 in terms of residue information. The results depend on the kind of residue involution and on whether the division algebra is inertially ...

Decomposition of involutions on inertially split division algebras [PDF]
Mathematische Zeitschrift, 2000 Let \(F\) be a Henselian valued field with residue field \(\overline F\) of characteristic not~\(2\) and let \(S\) be an \(F\)-central (finite-dimensional) division algebra which is split by an inertial extension of \(F\). Assume \(\sigma\) is an involution on \(S\) (i.e., an anti-automorphism of period~\(2\)) which is the identity on an inertial lift ...

Witt groups of Severi-Brauer varieties and of function fields of conics [PDF]
Épijournal de Géométrie AlgébriqueThe Witt group of skew hermitian forms over a division algebra $D$ with symplectic involution is shown to be canonically isomorphic to the Witt group of symmetric bilinear forms over the Severi-Brauer variety of $D$ with values in a suitable line bundle.
