Abstracts

Yu Min: Classicality of derived Emerton—Gee stack for general groups.

Abstract: In this talk, we will define the Emerton—Gee stack for a general group scheme using the Tannakian formalism and discuss its representability. Moreover when the group scheme is a generalised reductive group as defined by Paškūnas—Quast, we will define a derived version of the Emerton—Gee stack using prismatic theory and show how it is controlled by its underlying classical stack.
