Ryomei Iwasa - 15h30 - Cohomology of BGL_n

Salle Grisvard, IHP, Paris

The upshot of the theory of Chern classes is to understand the cohomology of BGL_n, and this is axiomatically (or motivically) achieved only from Zariski descent and projective bundle formula.
I will explain it from scratch. This is based on joint work with Toni Annala.
