Title: Prismatic Dieudonne theory and height 1 group schemes

Abstract: Prismatic Dieudonne theory relates finite flat group schemes to certain quasi-coherent complexes on stacks, called F-gauges.  I will explain how the F-gauges associated to height 1 group schemes can be described geometrically in quite explicit fashion, and that this description gives a geometric interpreation of several classical results in theory.  This is joint work with Shubhodip Mondal.
