Whitehead Groups of twisted free associative algebras

K. G. Choo

Vol. 50 (1974), No. 2, 399–402
Abstract

Let R be an associative ring with identity and X a set of noncommuting variables {xλ}λΛ. Let R{X} be the free associative algebra on X over R. Then S. Gersten has shown that if K1R K1R[t] is an isomorphism, where R[t] is the polynomial extension of R, then K1R K1R{X} is an isomorphism.

The purpose of this paper is to extend the result of Gersten to twisted free associative algebras.
