This is an introduction to mathematical treatment of Einstein's general relativity theory.
If you have taken or are taking the physics GR course, the two courses should complement each other nicely. In particular, there will not be much overlap. While a considerable part of the physics course is (probably) spent on introducing differential geometry, we will assume that the students are comfortable with basic differential geometry. Exact solutions with high degree of symmetry will be studied as prototypical examples of spacetimes, but our focus will be on the properties of realistic spacetimes with no or very little symmetry.
The following topics will be treated.
The grading will be based on a few homework, and a course project, where the student studies a specific topic and gives a presentation.
Grading: Homework 50% + Final project 50%.
