Homogeneous Spaces with Sections

manuscripta mathematica, 2005
We study homogeneous Riemannian manifolds all of whose geodesics can be mapped by some isometry into a fixed homogeneous, connected, totally geodesic submanifold, called section. We show that these spaces are locally symmetric if the section is two-dimensional and give non-symmetric counterexamples with higher-dimensional sections.

Homogeneous Spaces

2003
Publisher Summary In topology, for an arbitrary topological spaceX, the autohomeomorphism group Aut(X) consisting of all homeomorphism of X onto itself corresponds to such a group. Every group is isomorphic to the autohomeomorphism group of some compact Hausdorff space.
