This groundbreaking monograph in advanced algebra addresses crossed products, which involve group and ring theory. According to the author's Preface,crossed products have advanced from their first occurrence in finite dimensional division algebras and central simple algebras to a closer relationship with the study of infinite group algebras, group-graded rings, and the Galois theory of noncommutative rings. 1989 edition.
