Summary: Fantastic
Review: Concise and complete. I find myself coming to this book not only for Physics courses and Physics research, but I find it helpful in most Math courses. This book is a must for anyone in Physics and applied mathematics.

Summary: Beauty
Review: I have learnt from this mathematical book more physics that from many physics textbooks. I wish these guys wrote a book on differential geometry to save us time and money. Buy it while it is still available (at this price), it is a beauty.

Summary: The best ever
Review: If you are like so me, you have spent years torturing yourself with horrific books like Matthews and Walker or Arfken. But almost by accident I came across this absolute gem, this masterpiece of balance between rigor and informality. The book presents mathematical physics on a level that is exactly at the level of graduate physics. The notation, the viewpoint and the emphasis are exactly what you need to master just about all the mathematics in graduate physics. This is all done not as Afken or Matthews and Walker do it, by slapping together hodgepodges of this and that into a cookbook, but by unifying mathematical physics into a beautiful tapestry, with the underlying fabric of linear vector spaces.
This book would be worth it if the price were 10 times more than it is.

Summary: Terrific book to ramp up and read original papers
Review: If you're tired of reading descriptive physics like Paul Davies' books and want to be able to read the original papers and follow the math, this is the book. It presumes a strong undergraduate math background in some areas but the explanations are clear and the proofs are easy to follow. If you want to read quantum physics, the chapters on vectors and operators will give you the math foundations.

Summary: A lot of fun!
Review: The Byron & Fuller provides a serious introduction in mathematics of classical and quantum physics. This book is designed to complement graduate-level physics texts and one of its goal is to introduce the physicist to the language and style of mathematics. Consequently, this book may be really useful to people with strong skills in physics and maths. No doubt that they will have fun reading the theory of vector spaces.
For the others, just like me, not really specialized in physics and maths, but maybe just curious, this book can bring you a lot of fun too. It reminds you of what you may have studied a few years ago... And more than that, you cover with this book other fields of mathematics that are not taught to non specialized students like Hilbert space, quantum physics, theory of analytic functions, Green's functions and integral equations.To conclude, if you're curious about mathematics and physics, you should buy this book. If you're good at maths and physics, you should already own this book.
And now, with this special price, do the maths!

Summary: An introduction to the basic mathematics of physics
Review: This book introduces the reader to the basic mathematical structures of theoretical physics: mainly Quantum Mechanics, Electromagnetic Theory, And Classical Mechanics. I used this at UC San Diego for a year long graduate course on Mathematical methods in physics and engineering. If one has the time, there is really a lot to be gained by carefully studying this book. A big part of the book is geared toward developing in detail the mathematics of the Quantum Theory. This is a good thing because in my experience most QM books are too eager to "get to the physics". It is true that you can get by with a superficial understanding of functional analysis and still do QM, but this book will give you an immensely deeper understanding of the underlying structure of the theory. In particular, the treatment of Green's functions and integral equations is good. There is chapter on Group Theory and it's uses in QM. Also is a chapter on Complex analysis, although it is a wise idea to read a book entirely devoted to this subject. Overall, I like this book very much.

Summary: Important Information
Review: This book is not, and I repeat, IS NOT for the inexperienced. This book is a GRADUATE LEVEL TEXT on mathematical physics. If you are an undergraduate student taking a physics class, this book will be of no use to you. I recommend that anyone interested in purchasing this book have a somewhat decent amount of mathematical background. I personally recommend Calculus I-IV, Advanced Calculus and Linear Algebra.
If, though, you have this background, then this book is may just be for you. It is concise, to the point and presents a clear and well written discussion of mathematical physics.
I just felt that before you dive, head first, into the world of mathematical physics, somebody needed to warn you about what you were getting yourself into.

Summary: One of the Best
Review: This book was my very first introduction to mathematical physics; in fact, it was really my first introduction to either physics or math beyond the algebra level. At the time I bought it, when I was 9, the vast majority of the book was way, way, way above my head, but that did not stop me from reading it more and more, trying the best I could to make sense of it. I think it is a true testimony to the greatness of this set that it could hold the attention of someone who had no comprehension of about 90% of the material. In the course of almost eight years, I was inspired by this book to get material on calculus, first basic but then advanced, followed by many books on physics. It was largely because of these studies that I started college at 15, and again largely because of these studies that I am now getting A's in quantum field theory eight years later. I do not bring up these facts of my existance to impress people; if that were my intent, I would be ashamed to write this review. My intent is to give people an example which to some extent gives a slight indication of how wonderful this book is; I only hope that others enjoy this text as much as I do.
Personal stories aside, perhaps I should talk about specific details of this book. Every chapter is excellent, but I feel that some of them deserve special mention: chapters 5, 6, and 7. Chapter 5 is absolutely perfect, and contains a presentation of Hilbert spaces that is hard to find elsewhere. It is very unified, especially in its treatment of Sturm-Louiville polynomials; in other texts, the principal members of this set are given individual treatment, with little or no sense of unification, but here, the enlightening knowledge is revealed that they are all really the same thing, but with different weight functions. Chapter six is a fine treatment of analytic function theory, with special emphasis on the unifying Cauchy-Goursat theorem, and a precise discussion on which theorems imply others, what are the particularly strong results, and what are the most valuable techniques for the practising physicist in this vast field. Chapter 7 is an excellent introduction to Green's function theory, with special emphasis on the fact that the Green's function is not only determined by the differential equation, but also, and very importantly, by the boudary conditions. There are many other wonderful things about this book, but to express them all, I would have to write a book myself.
