Immortal homogeneous Ricci flows

In this talk we will report on recent progress towards a complete understanding of the Ricci flow in the homogeneous case. The main result states that for all homogeneous solutions which exist for all positive times, appropriate rescalings subconverge to self-similar solutions of the flow, so called Ricci solitons. Our main tool is a moment map interpretation of the Ricci curvature, which might be of independent interest. This is joint work with Christoph Böhm.
