Freedman Seminar: Michael Freedman, CMSA & Bowen Yang, CMSA
VirtualFreedman Seminar Speaker: Michael Freedman, Harvard CMSA Title: Sullivan's work on Lipschitz structures Abstract: I'll begin with an elementary, but now little known, piece of PL topology: engulfing. John Stalling used it to give an alternative proof of the high dimensional Poincare conjecture. Then I'll explain Dennis Sullivan's enhancement of Kirby's torus trick (which relies […]

Freedman Seminar: Michael Freedman, CMSA & Slava Krushkal, University of Virginia
HybridFreedman Seminar Speakers: Michael Freedman, CMSA and Slava Krushkal, University of Virginia (2-3 pm and 3:15-4:15 pm) Title: Formulating 4D surgery for AI agents Abstract: 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 […]
