Generalized normal homogeneous spheres
V. N. Berestovskiĭ Omsk Branch of Sobolev Institute of Mathematics, Siberian Branch of the Russian Academy of Sciences, Omsk, Russia
Abstract:
We find new generalized normal homogeneous but not normal homogeneous Riemannian metrics on spheres of dimensions $4n+3$, $n\ge1$, and all homogeneous space forms covered by them; all these spaces have zero Euler characteristic. Deriving consequences, alongside some other new results we obtain new proofs for analogous known results for all complex projective spaces of odd complex dimension starting from three.
Keywords:
geodesic orbit space, geodesic vector, $\delta$-homogeneous space, $\delta$-vector, naturally reductive space, (generalized) normal homogeneous Riemannian space, Riemannian submersion, weakly symmetric space, submetry.
