Mathieu Florence: Galois cohomology and essential dimension

Prof. Mathieu Florence from Universite Paris 6 (Jussieu) will visit us from April, 19 to May, 17. He will give a course about



'Galois cohomology and essential dimension'.



Here is the brief of the course:



In the beginning I plan to give a (more or less brief) overview about algebraic groups and their Galois cohomology, then switch to essential dimension: general properties and results, upper bounds for some algebraic groups, links with other fields in algebra. Then, I plan to explain some recent results, like my own (or its generalization by Karpenko and Merkurjev) on the essential dimension of cyclic p-groups, and even other results by Rost, or Brosnan-Reichstein-Vistoli, or Brosnan on essential dimension of elliptic curves over number fields, if I have time.
My idea was to give 3-4 hours of lectures a week, but I can also adjust this according to your preference.



The course is schedule every Tuesday and Thursday from 2:00-4:15 pm in MCM410.



All are welcome.
