SUMMARY:Some results about saturation
DESCRIPTION:Member Seminar \nSpeaker: Stephen Landsittel \nTitle: Some results about saturation \nAbstract: Given a local ring R we can ask when saturation of ideals in R commutes with other operations on ideals (such as extension to a ring containing R). We show that the condition that extension of ideals along a ring map R \to S commutes with saturation controls inherent properties of the rings R & S\, such as Cohen-Macaulayness and unramifiedness.

SUMMARY:Freedman Seminar: Michael Freedman\, CMSA & Slava Krushkal\, University of Virginia
DESCRIPTION:Freedman Seminar \nSpeakers: Michael Freedman\, CMSA and Slava Krushkal\, University of Virginia (2-3 pm and 3:15-4:15 pm) \nTitle: Formulating 4D surgery for AI agents \nAbstract: The topological category surgery exact sequence is still open for free groups (and most groups of exponential growth). The lack of knowledge is about both surgery and s-cobordism; and the source of the mystery is the same in both cases. Thinking about how to present this problem to AIs has had its own value. In a pair of talks we will explain how we have thought about the problem in the past and how we are thinking about it now.
