Johannes Anschutz (Sorbonne Université) 15h45 - 17h Prismatic cohomology

IHP
salle 314

I want to give a short introduction to the prismatic
cohomology of Bhatt/Scholze. After introducing the prismatic site, a
mixed-characteristic version of a crystalline site, I will focus on the
comparison of prismatic cohomology with crystalline and Hodge-Tate
cohomology.
