Title: Properties of flat cohomology via animated rings
Abstract: Flat cohomology encodes critical arithmetic phenomena in positive characteristic, yet its general properties remain largely undiscovered/undeveloped in comparison to étale or l-adic cohomology. In this series of talks, I will discuss an approach to attacking these properties with techniques from derived algebraic geometry and Dieudonné theory. The talks will be based on my joint work with Peter Scholze.

Title: Progress in syntomic cohomology
Abstract: The talks will present a survey of the (quasi)syntomic cohomology theory introduced by Bhatt, Scholze, and the speaker; this provides a variant of the syntomic cohomology of Fontaine, Kato, and Messing which has the advantage of being defined in a greater degree of generality and working well with torsion coefficients even for small primes. Although it underlies in principle a general theory of p-adic étale motivic cohomology, the talks will probably focus more on arithmetic aspects such as applications in p-adic Hodge theory. Based on various projects joint with Antieau, Bhatt, Clausen, Kelly, Lüders, Mathew, Nikolaus, and Scholze.
