The student or researcher who succeeds in reading this book will be rewarded with a deep understanding of the subject, both in the commutative and noncommutative setting. the book should stand on the shelf of anyone seriously interested in functional analysis and/or probability. (Stanisaw Goldstein, zbMATH, Vol. 1267, 2013)
This book is well written, with a concise, clear and readable style. It is divided into 3 chapters and includes a preface, a bibliography consisting of 98 items, and symbol, author and subject indexes.
