SUMMARY:Perfectoid Signature and Perfectoid Hilbert-Kunz Multiplicity
DESCRIPTION:Speaker: Hanlin Cai\, University of Utah\n\nIn this talk I'll talk about a (perfectoid) mixed characteristic version of F-signature and Hilbert-Kunz multiplicity by utilizing the perfectoidization functor of Bhatt-Scholze and Faltings' normalized length. These definitions coincide with the classical theory in equal characteristic. We prove …
