Model Theory Learning Seminar

Rahim Moosa, Department of Pure Mathematics, University of Waterloo

"NIP"

This learning seminar will be reading through parts of Pierre Simon’s book “A Guide to NIP Theories”. In this talk I will give a non-technical introduction to the subject, explaining some of the history and motivation behind considering these theories.

Geometry & Topology Seminar

Lukas Mueller, Perimeter Institute for Theoretical Physics

"Quantum representations of handlebody groups"

Mapping class groups of surfaces and handlebody groups are fundamental objects in low-dimensional topology.  Quantum algebra and mathematical physics provide large classes of finite dimensional representations for both.

Intersection Theory Learning Seminar

Changho Han, Department of Pure Mathematics, University of Waterloo

"Introduction to Intersection Theory II"

Continuing from where we left off, I will explain more properties of the chow ring along with more examples (such as Veronese embedding). Near the end, I will explain the first Chern class of a line bundle and draw connections to canonical divisors of various varieties.

This seminar will be held both online and in person:
