Pedagogically, I found this book wonderful. The way the material is exposed is insightful, and the book has proper typesetting. For the motivated reader (this is maths after all), it's a pleasant read.<br><br>One thing I'm not too happy about is the binding quality. I am usually pretty meticulous and careful with my books, and normally hardcover books of this type are very tough, but by the time I was done reading the first two chapters, the binding was broken in several places. Roughly half the pages seem to be hanging by a thread. This has never happened to me with any of the other Springer hardcover books in this format. My product shipped from India for some reason, so although it doesn't look counterfeit, a part of me wonders if I purchased the real thing. It's a crazy world we live in, who knows.
