Here are some things that I’ve translated into English. Any comments or corrections are greatly appreciated. I’ve tried to refrain from “rewriting” too much: generally the sentence structure etc. is pretty close to the original. Usually I don't have the time (or, truthfully, the energy) to fully proof-read everything after my first draft is done, so I'm sure that everything could be much improved. Sorry.

The following should go without saying, but I’ll say it anyway:
I am making no claim to any of the mathematics contained in any of these translations; the only things that are mine are the errors introduced during the hazardous journey from one language to another.
Further, these translations are for personal use only.

For each paper, there is a link to the .tex source file, to a PDF (nightly builds from the latest version of the .tex files), and to the original paper (if a copy is freely available online). Each PDF has a version hash so you can check at a glance if there have been any changes between two copies. (I will eventually put build dates on the PDFs.)

The GitHub repository with all these translations is [thosgood/translations].

Séminaire Bourbaki

Extracts (1948–49), "Les travaux de Koszul"

In the first series of the Séminaire Bourbaki, H Cartan gave three talks concerning the work of J-L Koszul on Lie algebras. (These specific talks were given in 1948–49, but the first published Séminaire Bourbaki collection was printed in 1952, containing the first 49 talks, and dating from 1948 up until 1951). I have combined all three talks into one document.

Extracts (1957–62), "Fondements de la Géométrie Algébrique"

The Grothendieck Circle has a PDF of the original notes. The translation below has been updated with the comments and errata from the May 1962 "Commentaires" (Séminaire Bourbaki 14, 1961–62, Complément).

All of the following are by A Grothendieck.

Schrift. 6 1958 28 p] is given instead. Talks number 5 and 6 [C Houzel Modules des surfaces de Riemann] in the same volume were also not written down.

Sometimes a paper takes "a while" to translate, but I put it here so that people can nudge me if there's one on this list that they really want me to get around to finishing. (Some of these I have barely started, so don't get too excited.)

Wish list

Translations which I have yet to start, but one day intend to, are listed here, so that I don't forget about them. Feel free to contact me with any suggestions! (I am particularly interested in finding some Spanish things to translate).
