Math 645: Riemannian Geometry


Course Description

This is a graduate level introduction to Riemannian geometry. Some basic familiarity with the theory of differential manifolds will be assumed, though there will be some review in the first two-three weeks. The course will follow J. Lee's "Riemannian Geometry". There will be 9-10 problem sets and no exams.

The course meets Tuesday and Thursday 10:30-11:45 on Zoom. See Blackboard for meeting details.

Problem sets will be due in class on Tuesdays (see below for dates).

Office Hours: By appointment on Zoom.
