# Book covering differential geometry and topology for physics

I'm interested in learning how to use geometry and topology in physics. Could anyone recommend a book that covers these topics, preferably with some proofs, physical applications, and emphasis on geometrical intuition? I've taken an introductory course in real analysis but no other higher math.

• I like Messer, Topology Now! It's easy and fun, and it gets you going on nontrivial stuff without a lot of prerequisites or worrying about what a physicist would consider pathological cases. – Ben Crowell Oct 15 '14 at 0:39

If you want to learn topology wholesale, I would recommend Munkres' book, "Topology", which goes quite far in terms of introductory material.

However, in terms of what might be useful for physics I would recommend either:

• Nakahara's "Geometry, Topology and Physics"
• Naber's "Topology, Geometry and Gauge Fields: Foundations"

Personally, I haven't read much of Nakahara, but I've heard good things about it, although it may presuppose too many concepts. I've read selections of Naber and it seems fairly well written and understandable and starts from first principles, but again, it may not focus as much on the fundamentals, if that's what you're looking for.

• Sorry, I haven't heard anything of that book. However, judging by the absolutely ridiculous price on Amazon... Anyway, I was also flipping through Nash and Sen's book, and it seemed to treat topology in a very intuitive and clear manner, although at a mathematical price - Amazon reviewers claim that it isn't too mathematically rigorous/comprehensive. – Nilay Kumar Jun 15 '12 at 8:40
• I enjoyed reading Nash and Sen, It suited my taste, being less formal, and more intuitive. Nakahara is nice. Schwarz seemed good at first glance, but I havent read it. – Prathyush Feb 14 '13 at 21:29
• You also asked about topics in topology relevant for physics. Apart from the basic definitions and so on, one of the most applied concepts is Homotopy. It is beautiful in itself, and it formalizes the concept of winding numbers to higher dimension. In physics it is commonly used to enumerate the topological solitons present in your theory.There are others, but I found Homotopy to be very important and useful. – Prathyush Feb 14 '13 at 21:39
• A reason for studying Naber's book -- If you want to delve into the subtleties of Dirac monopole, i.e. Hopf fibration of $S^3$ (which describes the geometry of the Dirac monopole), I would recommend you this book for sure. Nash and Sen is a good book, too. However, my personal favourite (apart from Nakahara) is "The Geometry of Physics," by Theodore Frankel. – Janus Boffin Apr 3 '16 at 10:27

The first thing that must be said is that the question is not really specific enough: Applications to what exactly are you looking for? To me, a book on algebraic geometry and mirror symmetry, and how it relates to mirror symmetry as physicists know it, is very relevant and interesting. However, I have the feeling that this is not exactly what you're looking for.

Therefore, I will mostly stick to "basic stuff", that seems relevant to anyone really interested in e.g. high energy physics (on the theory side of things, obviously), without assuming the reader is really interested in advanced stuff. However, I'll include a section of "specialized" books, where some more esoteric and/or difficult topics are included, as well as books that completely focus on one specific branch of physics (e.g. general relativity), rather than developing the general mathematical tools.

Finally, note that I'm omitting standard introductory texts for both topology & geometry if I feel the text is not really aimed specifically at physical applications, since there are so many that even with this stringent criterion there is enough left. Here we go (in alphabetical order):

## Basics

Baez & Muniain - Gauge Theories, Knots and Gravity

Interesting book that develops the mathematics along with the relevant physical theories: The first chapter is on E&M and the relevant mathematical notions such as forms, the second chapter is about gauge theory, both from the physical and mathematical perspective, and the last chapter is about general relativity and Lorentzian geometry.

Bleecker - Gauge Theory and Variational Principles

Starts with a very brief treatment of tensor calculus, fiber bundles etc, quickly moving on to physical topics such as Dirac fields, unification (of gauge fields) and spontaneous symmetry breaking.

Bredon - Topology and Geometry

After seeing the added message by QuanticMan, requesting answers not to shy away from going beyond the intentions of the OP and to recommend books with geometrical intuition, this book immediately sprang to mind. In the preface, Bredon states:

While the major portion of this book is devoted to algebraic topology, I attempt to give the reader some glimpses into the beautiful and important realm of smooth manifolds along the way, and to instill the tenet that the algebraic tools are primarily intended for the understanding of the geometric world.

This seems to perfectly fit the bill, and I can personally recommend it. Note, however, that it purely a book about mathematics: No applications to physics are presented, though the tools are of course relevant in physics, too.

Burke - Applied Differential Geometry

Starts with about 200 pages of mathematical tools (from tensors to forms) and then delves into applications: From the heat equation to gauge fields and gravity.

Cahill - Physical Mathematics

This is a really basic book, that does much more than just topology and geometry: It starts off with linear algebra, spends a lot of time on differential equations and eventually gets to e.g. differential forms.

Fecko - Differential Geometry and Lie Groups for Physicists

Develops the basic theory of manifolds (the focus is not on topology), and eventually treats a bunch of topics including classical mechanics (symplectic geometry), gauge theory and spinors. There is also a (much shorter) set of lecture notes by Fecko on the same topic.

Frankel - The Geometry of Physics: An Introduction

This is a big book that covers a lot of group mathematically, but does not really focus on physical applications. The topics include differential forms, Riemannian geometry, bundles, spinors, gauge theory and homotopy groups.

Gilmore - Lie groups, physics and geometry

Subtitled "An Introduction for Physicists, Engineers and Chemists", this book could be a good starting point for someone who is really only interested in simpler, down-to-Earth topics. Includes a chapter on "hydrogenic atoms", which sounds interesting.

Hamilton - Mathematical Gauge Theory: With Applications to the Standard Model of Particle Physics

I personally attended professor Hamilton's lectures, corresponding to approximately the first 450 pages of this book, and can vouch for the fact that everything in this book is presented with great care. It might be a bit overwhelming for someone who really only wants to focus on the physical applications, but many of the technical details of the background material that are often omitted in other texts are presented here in full. The second part is focused on physical applications, mostly to classical gauge theories. The text assumes some basic familiarity with manifolds, but not much else.

Isham - Modern differential geometry for physicists

A "standard introductory book" on differential geometry, translated to the language of physicists. Isham is careful to point out where mathematical notions that he introduces are used in physics, which is nice for those who prefer not to lose track of the physical relevance of it all. Covers all the basics up to fiber bundles in about 300 pages.

Jost - Geometry and Physics

Quickly gets to more advanced topics including moduli spaces, spinors and supermanifolds (all within the first 100 pages) in the first part, dedicated to mathematics. The second part is dedicated to physics and includes e.g. sigma models and conformal field theory.

Mishchenko & Fomenko - A course of differential geometry and topology

Though this is pretty much a "general introduction" book of the type I said I wouldn't include, I've decided to violate that rule. This book is Russian, and the style of Russian textbooks is very physical and interesting for physics students, in my opinion. Furthermore, the book does not focus on either differential geometry or topology, but covers both (briefly), which is also good for physics students.

Naber - Topology, Geometry and Gauge Fields (two volumes)

The first volume has a cute motivational chapter which introduces advanced notions (sadly, those are usually the ones that turn out to be relevant in physics), and first discusses homology & homotopy (in reverse order?!) before moving on to manifolds and bundles (also in reversed order?!), ending with (physical) gauge theory. The second volume covers more advanced topics such as Chern classes.

Nakahara - Geometry, Topology and Physics

The go-to book for mathematical prerequisites for e.g. gauge theory, string theory etc. if you ask 90% of physicists. I personally think it's terrible because it doesn't explain anything properly, but I guess it's good to learn buzzwords.

Nash & Sen - Geometry and Topology for Physicists

This book is not very physical, but seems very nice if you're really trying to get a good grip on the math. It takes its time to (properly, I hope) develop all the theory in order: fundamental group, homology, cohomology and higher homotopy groups are all introduced, before fiber bundles and then Morse theory and (topological) defects are treated (!!). The final chapter is on Yang-Mills theories, discussing instantons and monopoles.

Von Westenholz - Differential Forms in Mathematical Physics

After about 400 pages of preparatory mathematics (including, besides the standard topics, Frobenius theory and foliations, which is nice!), the book treats classical mechanics and relativistic physics (including fluid mechanics), each in about 50 pages.

Booss & Bleecker - Topology and Analysis: The Atiyah-Singer Index Formula and Gauge-Theoretic Physics

Advanced topic---very analytic, with lots of information on elliptic differential operators.

Cartan - Theory of Spinors

Couldn't resist putting this in: The original classic on spinors, by the discoverer himself. Kind of outdated (in e.g. notation) and therefore probably not very useful to modern students.

Deligne et al. - Quantum Field and Strings: A Course for Mathematicians (two volumes)

The two volumes cover about 1500 pages, with contributions from famous mathematicians and physicists alike (Deligne, Witten...). Covers lots of advanced topics in physics from a mathematical perspective, and includes exercises.

Dunajski - Solitons, Instantons and Twistors

Because the OP mentions solitons I thought this might be interesting to mention: Basic topology and geometry is assumed to be known, and a lot of physically interesting topics are covered (such as monopoles, kinks, spinors on manifolds etc)

Levi-Civita - The Absolute Differential Calculus

Another classic, and one of the first books on tensor analysis.

Nash - Differential topology and quantum field theory

This book seems fascinating for those who are really trying to get into the more difficult parts of gauge theory. Topics covered include topological field theories (knots invariants, Floer homology etc), anomalies and conformal field theory.

O'Neill - Semi-Riemannian Geometry With Applications To Relativity

A well-known textbook on the mathematical underpinnings of general relativity.

Sachs & Wu - General Relativity for Mathematicians

Same as the previous book

Ward & Wells - Twistor geometry and field theory

This book is completely dedicated to the theory of twistors: The last part is about applications to gauge theory.

• Which of these books did you like? Upon first sight, i really liked Frankel's Geometry of physics – TheQuantumMan Apr 12 '16 at 17:10
• @TheQuantumMan Frankel looks like one of the more serious books in the list. I think it could be nice. – Danu Jun 25 '16 at 22:01

For a new, concise, and very complete text with applications to many fields of physics, see Differential Topology and Geometry with Applications to Physics, by Nahmad-Achar (IOP Publishing). This book presents, in a concise and direct manner, the appropriate mathematical formalism and fundamentals of differential topology and differential geometry together with essential applications in many branches of physics.

Don't hurry ramanujan, learn basic mathematical methods first (from Sadri-Hassani's "Mathematical Physics" for instance). Then the standard reference for you to learn grad-level mathematics would be Nakahara's "Geometry, Topology and Physics". If you think it's too much, you're right; this is a very serious advanced topic. But if you want to quickly pick some basic ideas, check out the 10th chapter of Ryder's "Quantum Field Theory". An advanced and physically oriented discussion would be found in Coleman's "Aspects of Symmetry".

• What about Topology for physicists by Schwarz? – user7757 Jun 12 '12 at 10:56
