SUMMARY:Perfectoid purity for pairs
DESCRIPTION:Speaker: Anne Fayolle\, University of Utah\n\nIn positive characteristic, a ring is said to be F-pure if the Frobenius is a pure map. This can be extended to mixed characteristic by requiring the existence of a pure map to a perfectoid ring. We will discuss when and how we can extend this theory to pairs (R,D). This is based on joint work in …
