Preface
In the past 15 years, the theory of crossed products has enjoyed a period of
vigorous development. The foundations have been strengthened and anized
from new points of view, especially from the viewpoint of graded rings.
The purpose of this monograph is to give, in a self-contained manner, an up-
to-date account of algebraic structure of crossed products. Although no
