Generalized quaternion algebras
Rendiconti del Circolo Matematico di Palermo Series 2, 2023This paper is part of a small but growing circle of papers (including [\textit{E. Kizil} and \textit{Y. Alagöz}, Turk. J. Math. 43, No. 5, 2649--2657 (2019; Zbl 1431.16047)]) that study something they call ``generalized quaternion algebras'', which originate in [\textit{A. Mamagani} and \textit{M.

Generalized quaternion algebras
Mathematical Notes, 1993Es sei \(A\) ein kommutativer Ring, in dem 2 invertierbar ist. Zu invertierbaren Elementen \(a,b\in A\) sei \(Q=(a,b/A)\) die verallgemeinerte Quaternionenalgebra. Der Verf. zeigt, daß \(Q\) genau dann rechtsdistributiv ist, wenn \(A\) distributiv und die quadratische Form \(x^2-ay^2-bz^2\) nullteilig modulo jedem maximalen Ideal \(M\) von \(A\) ist ...

Algebras, Quaternions and Quaternionic Symplectic Groups
2002In this chapter we begin by studying algebras over a field, with their groups of units providing many interesting groups. In particular, we study division algebras and their linear algebra. Then we introduce the quaternions which form the only non-commutative example of a real division algebra.

The basic algebraic theory of quaternion algebras was given in Chapter 2. That sufficed for the results obtained so far on deducing information on a Kleinian group Γ from its invariant trace field kΓ and invariant quaternion algebra AΓ. We have yet to expound on the arithmetic theory of quaternion algebras over number fields.

The level of a ring R with 1 ≠ 0 is the smallest positive integer s such that −1 can be written as a sum of s squares in R, provided −1 is a sum of squares at all. D. W. Lewis showed that any value of type 2n or 2n + 1 can be realized as level of a quaternion algebra, and he asked whether there exist quaternion algebras whose levels are not of that ...
