"Curvature of generalized holomorphic bundles"

We continue with the discussion on generalized connections on a Riemannian manifold. We will discuss properties of curvatures on generalized holomorphic vector bundles over a generalized Kahler manifold and generalized analogues of classical notions.

The meetings of this learning seminar will continue on Tuesday afternoons, 2:30-4 pm, on Zoom. The plan for the next meeting is to wrap-up the discussion about the Fuglede-Kadison determinant and to move on towards the definition of the Brown spectral measure associated to an element of a W*-probability space.

The seminar will meet on Zoom.

"An introduction to toric varieties"

Toric varieties are a special kind of variety equipped with a group action from an algebraic torus. These varieties are very nice to work with because they have a combinatorial interpretation involving polyhedral geometry. I will (very quickly) introduce toric varieties and focus on some concrete examples.

The seminar will meet on Zoom.

The Brown measure was introduced by L.G. Brown in 1983. It is a generalized notion of spectral measure which applies to non-normal operators living in a suitable non-commutative probability framework -- the framework of a so-called W*-probability space. The purpose of this learning seminar is to provide an accessible entry point to the notion of Brown measure, with an eye towards becoming able to do calculations of Brown measures in examples which come from free probability.

"Counting Irreducible Polynomials with the Turán Sieve"

Sean Fitzpatrick, University of Lethbridge

"How using OER made me a better teacher"

I began working with open educational resources (OER) not long after my arrival at the University of Lethbridge. There were two immediate appeals: affordability (I could provide a textbook to students at no cost) and adaptability (I could edit the source to get the textbook I wanted). When the only commercial textbook we could find for a new course was over $300, I knew it was time to consider OER.

"Introduction to Elementary Sieve"

This talk aims at introducing sieve theory in an elementary way. Sieve problem and two elementary sieves  - larger sieve and square sieve - will be discussed in detail, as well as their applications and a broad overview of the historical development of sieve theory. Some standard results including the Mobius inversion formula will also be covered in this talk to make the proof self-contained.
