This question is motivated by this (highly recommended) comment by Emerton on Terry Tao's post "Learn and relearn your field". In particular, the following paragraphs:

In particular, the first couple of sections of Ribet’s famous Inventiones 100 article give a great example of how hundreds of pages of theory (including a lot of the theory of Neron models, and a quite a bit of SGA 7) can be summarized in ten or so pages of “working knowledge”.

and

For example, p-adic Hodge theory is another tool which plays a big role in a lot of arithmetic algebriac geometry, and which has a technically formidable underpinning. But, just like etale cohomology, it has a very nice formalism which one can learn to use comfortably without having to know all the foundations and proofs.

My question is: Do you know of other sources that provide useful manual for your favorite technical topic? (The kind of paper or section of a book which you use time and time again and would recommend for new researchers.)

As an example, where can I find the "nice formalism" of $p$-adic Hodge theory Emerton was referring to? (I was trying to learn more about almost ring theory from Gabber and Ramero — Almost ring theory and such a reference might be useful for bigger picture.)

Here is another example, just to fix ideas, since the question is a bit vague. At some point in graduate school I was trying to learn about "Riemann–Roch theorem for local rings". I found Fulton's intersection theory book, Chapter 18 and this paper by Kurano to be quite helpful.

This is obviously community wiki, so one topic per answer please. Answers with more description of the sources and how to use them would be very appreciated. Thanks a lot.

For symmetries of PDEs the book is Applications of Lie groups to differential equations by Peter Olver. In particular, in Chapters 4 and 5 one can find an excellent treatment of the celebrated theorem of Emmy Noether on the relationship of symmetries and conservation laws for Lagrangian systems. In contrast with some other books on the subject, this seminal theorem is presented there in full generality.

    $\begingroup$ Peter Olver's book is great, but I wouldn't call it a "manual" in the sense that Hailong is talking about. $\endgroup$ Apr 25, 2010 at 21:25

    $\begingroup$ Willie, IMHO, e.g. Chapter 5 of his book does match the OP's description ("the kind of paper or section of a book which you use time and time again and would recommend it for new researchers"). What makes you think otherwise? $\endgroup$ Apr 25, 2010 at 21:51

It's more a collection of facts than a user manual, and I could see an expert recommending to new researchers but probably not revisiting time after time themselves, but Maurizio Cailotto has a very useful reference sheet for logarithmic geometry.

I see that he also has reference sheets for other things like monoids and spectral sequences. For some reason the links are not working for me at the moment.
