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.
