Motivic stuff

Cohomology, homotopy theory, and arithmetic geometry

Blog silence because of Math Overflow…

Posted by Andreas Holmstrom on November 20, 2009

The last few weeks have been quite busy, and the spare moments that I would normally spend on blogging have been hi-jacked by Math Overflow. I wrote a few things there which I would normally have put on this blog, and since they might possibly be of interest to some blog readers, here are the links: Why are functional equations important, and What is the Yoga of Motives.

For quite a while, I have been trying (without much success) to understand finiteness properties for simplicial sheaves, and thanks to MO, I got an absolutely brilliant explanation from Denis-Charles Cisinski – something which simply could not have happened otherwise.  Lots of credit to MO (and to Cisinski)!
