"A trick involving biduals and an application"

I will present a trick involving biduals of C* algebras and present an application that derives proper proximality of all wreath products where the acting group is non amenable. This is joint work with Changying Ding.

This seminar will be held jointly online and in person:

"Introduction of conformal heat flow of harmonic maps"

In this talk I will present a new type of flow, called conformal heat flow of harmonic maps. In the first part I introduce known behavior of heat flow of harmonic map, including finite time bubbling. In the second part I introduce the conformal heat flow which is designed to delay such finite time singularities. Finally, I briefly show short time existence and future conjectures.

Thursday, March 3, 2022 — 1:00 PM EST

Christopher Lang, Pure Math Department, University of Waterloo

"The Spectral Curve of a SU(2) Monopole (Part 1): A Holomorphic Vector Bundle"

In this talk, we will be following Hitchin's 1982 paper, Monopoles and Geodesics, which defines spectral curves and discusses their relationship with SU(2) monopoles. This talk will focus on the creation of a holomorphic vector bundle on the space of oriented geodesics of R^3 as well as some of its properties.
