Abstract:

Abstract: In this series of talks, I will discuss work from three joint projects, with Vezzosi, with Bragg, and with Bhatt and Mathew, on Hochschild homology in characteristic p. Together these give a sense of when the Hochschild—Kostant—Rosenberg theorem is true in low dimension and what counterexamples in high dimensions. Along the way, we will also touch on the de Rham filtration on periodic cyclic homology as well as the filtration arising from the t-structure on cyclotomic structure, which is joint work with Nikolaus.
