It is a well-known phenomenon that mathematicians and physicists working on closely-related topics (say in gauge theories, or in general relativity etc.) generally approach the problems from very different angles and often have trouble understanding each other.

In this light, which book(s) do you wish theoretical physicists working on topics intersecting your own research area had read so they could more readily appreciate your work and/or more easily explain their own work to you in terms accessible to you?

To avoid this being opinion-based, please explain what essential concepts or techniques the theoretical physicist would learn from this book(s).

• The best Book about Geometry of Quantization I read in 2013-2014 was N. M. J. Woodhouse , Geometric Quantization, amazon.fr/Geometric-Quantization-N-M-Woodhouse/dp/0198502702

• I recall once hearing a physicist say that all functional analysts should read Dirac's Principles of Quantum Mechanics; he seemed sure that they had not all done so. Sep 16, 2020 at 15:51
• I somewhat dislike the implicit premise of this question, but maybe I am reading too much into it. My very inexpert impression is that theoretical physicists are actually ahead of most of us in using modern techniques. Sep 17, 2020 at 10:05
• @MarkWildon : I interpret the question to be analogous to a non-native speaker of English asking native English speakers for recommendations for a manual for idiomatic English that is geared toward speakers of English as a second language. Sep 17, 2020 at 16:50

"Les tenseurs" by Laurent Schwartz. This is the best book on the subject and I often feel that physics books do not really make a good job at presenting tensors. Too bad it has no English translation.

• Maybe I could translate it. Sep 22, 2020 at 18:24

• @user1741137 that would be great, but I suspect there are rights to be obtained before you can get started.

Quantum theory is an application of generalized probability theory (i.e., quantum logic). The most detailed introduction to this approach is: "Geometry of Quantum Theory", by V. S. Varadarajan https://smile.amazon.com/Geometry-Quantum-Theory-V-Varadarajan/dp/0387961240/ref=sr_1_3?crid=7P7GHVPJLJ95&dchild=1&keywords=varadarajan+quantum&qid=1600337321&sprefix=Varadarjan%2Caps%2C194&sr=8-3

Nakahara's Geometry, Topology and Physics.

It was chapter $$10$$ that allowed me to fully engage with connections on fibre bundles and the relationship to Gauge theories. The earlier chapters on Holonomy and de Rham Cohomology groups was instrumental in introducing these concepts from a Physics perspective for me in the early part of my PhD.

• typos, though... Sep 17, 2020 at 11:30
• @AlexArvanitakis Yes, unfortunately this is very true.... Sep 22, 2020 at 13:47
• Any hope for a revised edition?

I always thought spinors were treated in a quite obscure way in physics. In particular it's difficult to make sense of the Dirac adjoint $$\bar \psi= \psi^\dagger\gamma_0$$ of a spinor (take a look at the wikipedia entry if you don't believe me) until one reads an introductory book on Clifford algebras, particularly one which emphasizes the non-Euclidean case and the natural metric on spinors, like for instance Garling's.
