Thursday 17 Nov 2022Number Theory and Algebra Seminar: Overconvergent prismatic cohomology

Prof. Andreas Langer - University of Exeter

Harrison 203 14:30-16:30

Abstract: In my talk I will define an overconvergent version of prisms and prismatic cohomology as introduced by Bhatt and Scholze and show that overconvergent prismatic cohomology specializes to p-adic cohomology theories, like Monsky-Washnitzer resp . rigid cohomology for smooth varieties over a perfect field, the de Rham cohomology of a smooth weak formal scheme over a perfectoid ring and the etale cohomology of its generic fibre.
