The existence of homogeneous geodesics in homogeneous pseudo-Riemannian and affine manifolds

It is proved that any homogeneous affine manifold (and, as a corollary, any homogeneous pseudo-Riemannian manifold) admits at least one homogeneous geodesic through any point....

On a Generalization of Curvature Homogeneous Spaces

Sekigawa proved in 1977 that a 3-dimensional Riemannian manifold which is curvature homogeneous up to order 1 in the sense of I.M. Singer is always locally homogeneous. We deal here with the modification of the curvature
