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.

Decomposition of Riemann curvature in 4 dimensions (and beyond?)
This is a continuation of my earlier talk from May. We showed that the Riemann curvature tensor of a Riemannian metric decomposes into three orthogonal components: the scalar curvature, the traceless Ricci curvature tensor, and the Weyl curvature tensor. We will see that in dimension 4 we can say more. The Weyl curvature decomposes into two pieces, and we will explicitly determine the decomposition the curvature operator (as a self-adjoint operator on 2-forms). As an application, we will discuss the Singer-Thorpe Theorem characterizing 4-dimensional Einstein metrics in terms of this decomposition. If time permits, we will briefly discuss a generalization of these ideas to G2-geometry in seven dimensions.
