A NON-COMMUTATIVITY STATEMENT FOR ALGEBRAIC QUATERNIONS

International Journal of Algebra and Computation, 2006
We prove a constructive version of Tits' alternative for groups of quaternions with algebraic coefficients by bounding valuations of their entries considered as elements of a fraction field of an opportunely chosen Dedekind domain.

On Non-Commutative Algebras and Commutativity Conditions

Results in Mathematics, 1990
A theorem of T. Nakayama states that an algebra \(A\) over an \({\mathcal N}\)- ring \(R\) is commutative if \(A\) satisfies the following condition: (N) For each \(x\) in \(A\), there exists \(f(X)\) in \(X^ 2 R[X]\) such that \(x-f(x)\) is central. More generally, W. Streb studied \(R\)-algebras \(A\) satisfying the following condition: (S) For each \

Non-Commutative Algebra

The Mathematical Gazette, 1928
The whole of ordinary algebra, dealing with real or complex numbers a, b, c, is based on three fundamental laws which are usually called: I. The Associative Law, II.
