Title: Not so good
Review: It is simple to echo the review that the exposition is not very clear and that the book should present more examples. Further, though, I would disagree with the reviewer who comments that the notation is consistent. In short, this book should be read only by those who already have an absolute grasp on the material, because the book is written for them.
