KA2W01 - Algebraic K-theory, motivic cohomology and motivic homotopy theory

In this talk I will discuss an analogue of the classical HKR theorem in the context of logarithmic geometry. The proof is based on a description of logarithmic Hochshild Homology (as defined by Rognes) in terms of the “replete log diagonal”, inspired by the work of Kato and Saito.  This is a joint work (in progress) with Tommy Lundemo, Doosung Park, and Paul Arne Østvær.
