    Abstract

    We classify compact asystatic G-manifolds with xed point singular orbits in cohomogeneity  3 up to equivariant di eomorphism. From this we derive existence results for invariant metrics of positive Ricci curvature on such objects. We also develop non-existence results for invariant metrics of positive Ricci curvature in cohomogeneity four.
