摘要
In this talk we will discuss Einstein manifolds invariant under an isometric Lie group action. Our main goal is to explain the proof of the Alekseevskii conjecture (1975) for homogeneous Einstein spaces of negative Ricci curvature, recently obtained in joint work with C. Böhm (Münster). To that end, we will also present new structure results for Einstein metrics on principal bundles. We will conclude with some open questions and future directions.
