On central division algebras

Israel Journal of Mathematics, 1972
For any integern such that 8|n or for which there exists an odd primeq such thatq 2|n, there is a central division algebra of dimensionn 2 over its center which is not a crossed product. The algebra constructed in this paper is the algebraQ(X 1,…,X)m, the algebra generated over the rationalQ bym(≧2) generic matrices.

The double centralizer theorem for division algebras

Israel Journal of Mathematics, 1983
Die Autoren beweisen den folgenden Satz: Sei D ein Körper mit Zentrum F, \(T\in M_ n(D)\) algebraisch über F. Dann ist der Doppelzentralisator C(C(T)) von T in \(M_ n(D)\) gleich F[T]. Der Beweis geht wie im kommutativen Fall aus von dem Modul \({}_ RV\) über dem Hauptidealring \(R=D[X]\), wobei \({}_ DV\) ein Vektorraum der Dimension n ist und X wie ...

Biquaternion division algebras and fourth power-central elements

Journal of Pure and Applied Algebra, 2022
This paper concerns the conditions under which a bi-quaternion algebra is a cyclic algebra (of degree 4) over its center. When \(F\) is a field of \(\operatorname{char}(F)=2\), it is known that every bi-quaternion algebra is a cyclic algebra [\textit{A. A. Albert}, Am. J. Math. 56, 75--86 (1934; Zbl 0008.24202)].
