Introduction to Einstein Manifolds and the Ricci Flow
In this course we'll introduce the concepts of Einstein manifolds and Ricci
flow and present some basic results in these two directions. The following is
a list of topics on the plan:
1. Basic properties of the Einstein equation. Gauge fixing and ellipticity.
2. The total scalar curvature functional and its relation to Einstein metrics.
Its first variation and second variation.
3. Decomposition of the Riemann curvature tensor.
4. Locally conformally flat manifolds. The conformal Laplacian. Introduc-
tion to the Yamabe problem.
5. Obata's theorem.
6. The total scalar curvature functional on asymptotically flat manifolds.
7. Topology of Einstein 4-manifolds.
8. Short time existence of the Ricci flow.
9. Perelman's entropy functional, the log entropy functional of Ye and non-
