Thomas Nikolaus: K-theory of Z/p^n and relative prismatic cohomology

We will explain how to compute the K-theory of rings of the form Z/p^n. Central for this is the notion of a prism and of prismatic cohomology following Bhatt-Scholze. We will explain how to extend this notion to a more general setting and how to characterize it by a universal property (relative to so-called generaralized prisms, which are a higher categorical version of prisms).
