"Curvature of almost Hermitian manifolds"

Let $(M, g, J)$ be a Riemannian manifold with $g$-orthogonal almost complex structure $J$. The Riemann curvature tensor satisfies certain identities involving the torsion $\nabla J$. We will focus on the Kahler case (when $\nabla J = 0$) and if time permits we will make some remarks about the general case.

This seminar will be held jointly online and in person:

"Teaching and learning roles in extremely large math courses"

Starting next year, the Math Department at UBC will teach extremely large consolidated courses of around 4000 undergraduate students each. In this talk, I'll describe how we've split the jack-of-all-trade "instructor" role into dedicated specialist roles, with the goal of improving the experience for everyone involved -- especially the students.

"Integrality theorems for symmetric instantons"

A symmetric instanton is a solution to the finite-energy anti-self-dual instanton equation on R^4 in which the connection commutes with some perscribed group of symmetries. This talk introduces the symmetric ADHM equations for structure group SU(N), and how index-theoretic methods can be used to derive integrality theorems for different symmetry groups.

"Intro to calibrated geometry"

I will give a brief introduction to the ideas of calibrated geometry, as introduced in 1982 by Harvey-Lawson. In particular I will focus on the Kahler, special Lagrangian, and associative calibrations.
