expose -> exposé, while this is on the front page

I am much more inclined to express my admiration and gratitude for the authors of SGA, rather than complaining about ways in which they may have fallen short. | |

| Oct 20, 2010 at 20:21 | comment | added | Jérôme Poineau | In the note arxiv.org/abs/math/0506589, Daniel Ferrand explains why the exposé XI of SGA 6, of which he was in charge, is missing. In short, he found a problem in the exposé (due to the non additivity of the trace in derived categories), which would have forced him to redo everything in a new setting (using ideas of Deligne) and he somehow lost interest in it. | |

I don't know, but I can well imagine, that some exposes were lost (in that the paper manuscripts were lost), others were never written, and others were written but not typed. To get some sense of the atmosphere surrounding their writing, you can read this interview with Luc Illusie. | |
