From the reviews:
"The study of idempotent elements in the group algebras originates from geometric and analytic considerations. … This book provides an introduction to the study of these problems for graduate students and researchers … . collects and presents in a systematic way basic techniques and important results that have been obtained during the past few decades. … The book is suitable for independent study … . Moreover, all chapters and appendices finish with a sufficient number of exercises that also increase the quality of the book." (S. V. Mihovski, Zentralblatt MATH, Vol. 1093 (19), 2006)
