The topic of this book, graded algebra, has developed in the past decade
to a vast subject with new applications in noncommutative geometry and
physics. Classical aspects relating to group actions and gradings have
been complemented by new insights stemming from Hopf algebra theory. Old
and new methods are presented in full detail and in a self-contained
way. Graduate students as well as researchers in algebra, geometry, will
find in this book a useful toolbox. Exercises, with hints for solution,
provide a direct link to recent research publications. The book is
suitable for courses on Master level or textbook for seminars.
