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. Please contact me with any corrections or comments, either by email or through the GitHub repository @thosgood/translations (where you can also find all source files).

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. All translations on this page are for personal use only.

(Note that I only translate things that are already freely available online.)

Seminars

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.

Séminaire Henri Cartan, Volume 13 (1960–61), "Familles d'espaces complexes et fondements de la géométrie analytique"

The first talk (Douady, A. "Fibrés en tores complexes") of the 1960–61 Séminaire Henri Cartan appears to have been lost to the past: the complete list of talks from the edited second edition says that no copies of the notes were made, suggesting that the reader instead refer to an article [Atiyah M.F. "Some examples of complex manifolds". Bonner math. Schrift. 6 (1958)]. Here I have translated the next three talks.

The "Grothendieck trilogy"

The three large treatises on algebraic geometry are all, well, large. Because of this, their translations form projects that will last for quite a few years yet to come. None of them are fully finished yet, nor will they be any time soon.

In progress

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.)
