Shapes

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.

Differential Geometry Working Seminar

Spiro Karigiannis, University of Waterloo

A tale of two Lie groups

The classical Lie group SO(4) is well-known to possess a very rich structure, relating in several ways to complex Euclidean spaces. This structure can be used to construct the classical twistor space Z over an oriented Riemannian 4-manifold M, which is a 6-dimensional almost Hermitian manifold. Special geometric properties of Z are then related to the curvature of M, an example of which is the celebrated Atiyah-Hitchin-Singer Theorem. The Lie group Spin(7) is a particular subgroup of SO(8) determined by a special 4-form. Intriguingly, Spin(7) has several properties relating to complex Euclidean spaces which are direct analogues of SO(4) properties, but sadly (or interestingly, depending on your point of view) not all of them. I will give a leisurely introduction to both groups in parallel, emphasizing the similarities and differences, and show how we can nevertheless at least partially succeed in constructing a "twistor space" over an 8-dimensional manifold equipped with a torsion-free Spin(7)-structure. (I will define what those are.) This is joint work with Michael Albanese, Lucia Martin-Merchan, and Aleksandar Milivojevic. The talk will be accessible to a broad audience.

Geometry and Topology Seminar

Mingyang Li, UC Berkeley

On 4d Ricci-flat metrics with conformally Kahler geometry.

Ricci-flat metrics are fundamental in differential geometry, and they are easier to study when they have additional structures. I will introduce my recent work on 4d conformally Kahler but non-Kahler Ricci-flat metrics, which is a condition analogous to hyperkahler. This leads to a complete classification of asymptotic geometries of such metrics at infinity and a classification of such gravitational instantons.
