SUMMARY:The arc-topology
DESCRIPTION:Speaker: Akhil Mathew\, University of Chicago\n\nI will discuss a Grothendieck topology on the category of quasi-compact quasi-separated schemes called the "arc-topology." Covers in the arc-topology are tested via rank <=1 valuation rings. This topology is motivated by classical questions in algebraic K-theory, and leads to Mayer-Vietoris style …

SUMMARY:A theorem about maximal Cohen-Macaulay modules
DESCRIPTION:Speaker: Thomas Polstra\, University of Utah\n\nIn this talk we will discuss a surprising uniform property concerning the class of Cohen-Macaulay modules over strongly F-regular rings. As an application, we show that the torsion subgroup of the divisor class group of a local strongly F-regular ring is finite.

SUMMARY:Inversion of adjunction for F-signature
DESCRIPTION:Speaker: Gregory Taylor\, University of Illinois at Chicago\n\nStrongly F-regular inversion of adjunction is the positive characteristic analog of the klt/plt inversion of adjunction in birational geometry. In characteristic 0, the klt/plt inversion of adjunction statement can made quantitative with the normalized volume. In this talk, we discuss an analogous …
