Abstract

Let X be a set and k a field. We show the so-called JF-embeddings of k 〈 X 〉 in a division ring have inversion height at most two, and give examples of inversion height one and two. We use these embeddings to obtain embeddings of the free group algebra in a division ring of inversion height one and two. © 2006 Elsevier Inc. All rights reserved.
