MAT 645 |
Prof. Claude LeBrun.
Office: Math Tower 3-108.
Office hours: TΘ 2:00--3:30 pm.
This is the second semester of a year-long course on twistor correspondences in Riemannian and pseudo-Riemannian geometry. We will now see how techniques similar to those explored last semester can also shed light on Riemannian metrics of special holonomy, manifolds whose geodesics are all closed, and the Einstein-Weyl equations in Lorentz signature.
A good understanding of last semester's lectures would be helpful, but may not be absolutely necessary. On the other hand, the lectures will certainly presuppose some basic knowledge of Riemannian geometry and complex manifold theory, and students without this sort of background may not be able to follow the discussion.
Grades will be based upon attendance and class participation.
