Geodesic orbit metrics in a class of homogeneous bundles over quaternionic Stiefel manifolds
(2021)Geodesic orbit spaces (or g.o. spaces) are defined as those homogeneous Riemannian spaces (M=G∕H,g) whose geodesics are orbits of one-parameter subgroups of G. The corresponding metric g is called a geodesic orbit metric. ... -
Geodesic orbit metrics in a class of homogeneous bundles over real and complex Stiefel manifolds
(2021)Geodesic orbit spaces (or g.o. spaces) are defined as those homogeneous Riemannian spaces (M= G/ H, g) whose geodesics are orbits of one-parameter subgroups of G. The corresponding metric g is called a geodesic orbit metric. ... -
