Abstract:
Note special place: Lunt 104. In this talk, we will discuss an approach to de Rham cohomology in the p-adic context using group schemes and similar concrete structures. I will mention the compatibility with the previous approach with the more abstract stacky approach to de Rham cohomology due to Drinfeld. Then I will explain the classification of all the endomorphisms of de Rham cohomology and a proof of the recent refinement of Delligne-Illusie decomposition (due to Drinfeld and Bhatt-Lurie) using this approach obtained in joint work with Shizhang Li.Date: Monday, September 27, 2021
