From the reviews: "The book, according to the authors, originated in a course of lectures by D. Husemoller for physics students at the LMU in Munchen during summer term 2003. ... The book is suitable for those readers who want to learn this subject rapidly, even if they are newcomers to this field, and also for the sake of the interest in twisted K-theory this book will be stimulative even to the readers who have already studied Husemoller's book ... ."
