However, the book is not well written and organized. Some expressions can only be understood by the authors themselves. The readers have to be prepared to spend much more time than they expect to figure out some minor details. Examples lack of step-by-step description. Important details are either missing or skipped in many places, assuming the readers are super-mathematicians.

The book is, I would say,~~ out of a rush-to-publish job. Looking forward to 2nd Edition, if there is one.~
