Cohomology, homotopy theory, and arithmetic geometry

Ofer Gabber and Carlos Simpson

Posted by Andreas Holmstrom on January 19, 2009

Also on Monday, Carlos Simpson talked about descent, and Ofer Gabber talked about finiteness theorems in etale cohomology. I don’t have very coherent notes from these talks, so I will only point to the abstracts (Gabber and Simpson), both of which are very informative (2 pages each) and much more coherent than anything I could post myself. For Gabber’s rather technical results on finiteness theorems, see also the notes by Joel Riou from a study group in Paris.

I hope to come back to the notion of descent in some future posts, when I have understood it better.
