Logic Seminar

Shaun Allison, University of Toronto

"Treeable CBERS are classifiable by an abelian Polish group"

Thursday, September 21, 2023 1:00 pm - 1:00 pm EDT (GMT -04:00)

Kirby Calculus Seminar

William Gollinger, University of Waterloo

"Handles II"

This week we continue the discussion of handles, moving on to handle decompositions of smooth manifolds. We briefly describe how Morse Theory ensures the existence of handle decompositions, and give some particular examples. We discuss in some detail the notions of dual decompositions, handle cancellations, and handle slides.

Intersection Theory Learning Seminar

Organizational Meeting

We will discuss/determine the time this seminar will be held this term as well as determine the first set of speakers. This seminar will follow a portion of the book "3264 and all that: the second course in algebraic geometry" by Eisenbud and Harris. A co-organizer (Changho) will also give a brief teaser of the seminar, as well as explain how to read the book (and prepare the talks).
