June 2022

Wednesday, June 1, 2022 — 9:30 AM EDT

Talk #1 (9:30 - 10:45 am): Daren Cheng, Department of Pure Mathematics, University of Waterloo

"A strong stability condition on minimal submanifolds and its implications, Part 2"

Parker Glynn-Adey, University of Toronto, Scarborough

"Teaching Strategies from Positive Psychology"

Positive psychology is the study of happiness, well-being, autonomy, and other positive aspects of the human experience. It is best known in math education through growth mindset and the work of Carol Dweck. In this talk, we'll work on some simple and scattered teaching strategies inspired by positive psychology.

Wednesday, June 8, 2022 — 9:30 AM EDT

Talk #1 (9:30 am - 10:45 am): Amanda Petcu, Department of Pure Mathematics, University of Waterloo

"Introduction to Kahler geometry, part 2"

We will continue with the basics of complex geometry to build the necessary knowledge for studying Kahler geometry. More precisely we will talk about holomorphic forms and vector fields and, certain theorems that relate to integrability of the manifold and almost complex structures.

Tuesday, June 14, 2022 — 1:30 PM EDT

Austin Sun, Department of Pure Mathematics, University of Waterloo

"Two Proofs of the Generalized Bézout's Theorem - Part II"

Wednesday, June 15, 2022 — 9:30 AM EDT

Talk #1 (9:30am - 10:30am): Anton Iliashenko, Department of Pure Mathematics, University of Waterloo

"Some results about Riemannian submersions"

We will go through some results about Riemannian submersions from the Arthur L. Besse's book on Einstein manifolds. For example, we will show that a surjective Riemannian submersion is harmonic iff the fibers are minimal, and some others as the time permits.

Talk #2 (10:45am - 12:15pm): Jean-Pierre Bourguignon, President, European Research Council

Thursday, June 16, 2022 — 1:00 PM EDT

Xinli Wang, University of Manitoba

"Mastery-based grading in a second-year mathematics course"

Thursday, June 16, 2022 — 2:30 PM EDT

Spencer Whitehead, Department of Pure Mathematics, University of Waterloo

"Introduction to principal bundles"

In this talk we will cover the basic theory of principal bundles and their relation to vector bundles via the frame and associated bundle constructions. We will define connections on principal bundles and structure group reductions, and then if time permits introduce the groups Spin(n) and spin structures on manifolds.

MC 5403

Wednesday, June 22, 2022 — 9:30 AM EDT

Talk #1 (9:30am - 10:45am): Amanda Petcu, Department of Pure Mathematics, University of Waterloo

"Isometric Immersions, part 1"

This series of talks will cover Chapter 6 of Manfredo Do Carmo's book 'Riemannian Geometry'. In this specific talk we will introduce the notion of an isometric immersion and the second fundamental form. We will see some examples as well as some properties of isometric immersions and the creation of the second fundamental form for a Riemannian manifold. 

Wednesday, June 22, 2022 — 2:30 PM EDT

Benjamin Anderson-Sackaney, Department of Pure Mathematics, University of Waterloo

"Multipliers on Fourier Algebras"

We will give a brief introduction to multipliers on the Fourier algebra of a locally compact group. Then we will discuss weak amenability, which is a weakening of amenability from the perspective of Leptin's theorem. It was shown by Haagerup that, though free groups are non-amenable, they are weakly amenable. The finale will proceed by outlining a proof of this theorem.

MC 5403

Wednesday, June 22, 2022 — 4:00 PM EDT

Sabrina Lato, Department of Combinatorics & Optimization, University of Waterloo

"Perron, Frobenius, and some unexpected applications"

Thursday, June 23, 2022 — 2:30 PM EDT

Spencer Whitehead, Department of Pure Mathematics, University of Waterloo

"Spin and Spinors"

We will define the groups Spin and Pin, the spinor representation, spin structures, and spinor bundles. As time permits we will look at some examples of spin structures and topological obstructions to spinnability. 

MC 5403

Tuesday, June 28, 2022 — 1:30 PM EDT

Yash Singh, Department of Pure Mathematics, University of Waterloo

"The Arithmetic of the Brauer-Manin Obstruction"

We study the Hasse principle on the existence of rational points on varieties and the Brauer-Manin obstruction which in some cases explains the failure of the Hasse principle.

This seminar will be held jointly online and in person:
