Abstract
Let k be a field. A projective Schur Algebra over k is a finite-dimensional k-central simple algebra which is a homomorphic image of a twisted group algebra k(alpha)G with G a finite group and alpha is-an-element-of H-2(G, k *). The main result of this paper is that every projective Schur division algebra is an abelian crossed product (K/k, f), where K is a radical extension of k. (C) 1994 Academic Press, Inc.
