We will follow, with some minor modifications, the Bonn syllabus from one year ago to study the paper on prismatic Dieudonn'e theory from Anschütz and Le Bras [1], concluding with an addendum for Mondal’s paper [3] on the stacky approach to the theory.

The seminar meets from 1300 to 1500 central time on Thursdays.
