Pre-requisites

Knowledge concerning the following topics would be helpful:

• Basic Riemannian geometry (Riemannian metric, Levi-Civita connection, Riemannian curvature tensor –> do Carmo, “Riemannian geometry”)
• Homogeneous spaces (Cheeger-Ebin, “Comparison Theorems in Riemannian Geometry”, important for section 3 of this unit)
• Ordinary differential equations (Perko, “Differential equations and dynamical systems)
