Admissible groups, symmetric factor sets, and simple algebras

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1984
Let K be a field of characteristic zero and suppose that D is a K-division algebra; i.e. a finite dimensional division algebra over K with center K. In Mollin [1] we proved that if K contains no non-trivial odd order roots of unity, then every finite odd

Algebras over a Field and Semantics for Context-Based Reasoning [PDF]

open access: yes, 2013
This paper introduces context algebras and demonstrates their application to combining logical and vector-based representations of meaning. Other approaches to this problem attempt to reproduce aspects of logical semantics within new frameworks. The approach we present here is different: We show how logical semantics can be embedded within a vector ...

A cancellation theorem for projective modules over affine algebras over C1-fields

open access: yesJournal of Pure and Applied Algebra, 2003
Let \(k\) be a \(C_1\)-field, that is for every homogeneous polynomial \(F(x_1,x_2,\dots, x_n)\) of the degree \(d< n\) the equation \(F(x_1,x_2,\dots, x_n)= 0\) has a nontrivial solution in \(k^n\). Assume that \(\text{char\,}k= 0\), \(A\) is an affine algebra over \(k\) of (Krull) dimension \(d>1\) and \(P\) is a finitely generated projective \(A ...
