Welcome to Pure Mathematics

We are home to 30 faculty, four staff, approximately 60 graduate students, several research visitors, and numerous undergraduate students. We offer exciting and challenging programs leading to BMath, MMath and PhD degrees. We nurture a very active research environment and are intensely devoted to both ground-breaking research and excellent teaching.


News

More than 100 researchers and students from across Canada and around the world attended the 53rd annual Canadian Operator Algebras Symposium (COSY), which took place from May 26-30 at the University of Waterloo.

Differential Geometry Working Seminar

Spiro Karigiannis, University of Waterloo

Decomposition of the Riemann Curvature Tensor

The Riemann curvature tensor R of a Riemannian metric decomposes into three orthogonal components: thescalar curvature, the traceless Ricci curvature tensor, and the Weyl curvature tensor. I will explain in detail therepresentation theory and linear algebra underlying this decomposition. Moreover, we will see that in the specialcases of dimensions 2, 3, 4 one can say more. As an application, I will discuss the Singer-Thorpe Theoremcharacterizing Einstein metrics in 4 dimensions in terms of this decomposition. If time permits (and it may wellpermit, as this will be a 2.5 hour talk with a break midway), I will briefly discuss a generalization of these ideasto G2-geometry in 7 dimensions.

Algebraic Geometry Working Seminar

Kaleb Ruscitti, University of Waterloo

Building Kronecker Moduli Spaces

Kronecker moduli spaces are quiver moduli spaces and a generalization of Grassmannians. They parameterize n-tuples of matrices between two vector spaces, up to change of basis on both sides. In this seminar, I will describe how to construct them as GIT quotients and what properties we can prove about them from this construction.

Ergodic Theory Learning Seminar

Julius Frizzell, University of Waterloo

A Quick Introduction to Ergodic Theory

I will introduce the basic definitions and theorems (without proof) of ergodic theory that are needed to discuss Furstenberg's multiple recurrence theorem. The development will follow that in Chapter 1 of "An Introduction to Ergodic Theory" by Peter Walters and Chapter 3 of "Multiple Recurrence in Ergodic Theory and Combinatorial Number Theory" by Harry Furstenberg. Time allowing, I will also cover the statement of the Multiple recurrence theorem itself and its relationship to Szemerédi's theorem.
