The other reviews must either be the work of idiots or the publisher of the book.
First of all, this book has NO proofs. It doesn't even have exact definitions and formulations of theorems.
It is a bloated mess - the author doesn't even manage to define what a complex number is.
The only redeeming quality of this book are the frequent references to other books - the author at least now and then must feel guilty about the garbage he is writing, and so he refers you to his betters.
