Abstract

We classify homogeneous Einstein metrics on compact irreducible symmetric spaces. In particular, we consider symmetric spaces with $\operatorname{rank}(M) > 1$, not isometric to a compact Lie group. Whenever there exists a closed proper subgroup G of $\operatorname{Isom}(M)$ acting transitively on M we find all G-homogeneous (non-symmetric) Einstein metrics on M.
