Homogeneous geodesics in homogeneous Randers spaces -- examples

2020
Summary: In this paper, we study homogeneous geodesics in homogeneous Randers spaces. we give a four dimensional example and we obtain homogeneous geodesics of this space in some special cases.

Integrable geodesic flows on homogeneous spaces

Sbornik: Mathematics, 2001
Consider a compact Lie group \(G\) endowed with a bi-invariant metric, a closed subgroup \(H\), and the homogeneous space \(M= G/H\), endowed with its geodesic flow \(O\). Let \(f_1,\dots, f_\ell\) be a basis of \(O\)-invariant real functions on \(T^1M\). For \(x\in M\), consider the subspace \(F_x\) of \(T^*_x M\) spanned by \(df_1(x),\dots, df_\ell(x)

Homogeneous Riemannian manifolds with only one homogeneous geodesic

Publicationes Mathematicae Debrecen, 2003
Summary: \textit{O. Kowalski} and \textit{J. Szenthe} [Geom. Dedicata 81, No. 1-3, 209--214 (2000; Zbl 0980.53061), Erratum ibid. 84, 331--332 (2001)] proved that each homogeneous Riemannian manifold \((M, g)\) admits at least one homogeneous geodesic, i.e., a geodesic which is an orbit of a one-parameter group of isometries.

Light-like homogeneous geodesics and the geodesic lemma for any signature

Publicationes Mathematicae Debrecen, 2007
Summary: Homogeneous geodesics on homogeneous Riemannian manifolds have been studied by many authors. The fundamental tool is the so-called geodesic lemma. On pseudo-Riemannian manifolds, a generalization of the geodesic lemma is necessary. Physicists already know and use the generalized version.

Geodesic symmetries of homogeneous K�hler Manifolds

Geometriae Dedicata, 1981
D'Atri and Nickerson [6], [7] have given necessary conditions for the geodesic symmetries of a Riemannian manifold to preserve the volume element. We use their results to show that ifG is a compact simple Lie group,T is a maximal torus ofG, andG/T is not symmetric, then anyG-invariant Kahler metric onG/T does not have volume-preserving geodesic ...

Geodesics and Jacobi Fields in Bounded Homogeneous Domains

Proceedings of the American Mathematical Society, 1983
The authors study bounded homogeneous domains in \({\mathbb{C}}^ n\) endowed with the Bergman metric. In case D is symmetric it is well known that the sectional curvature is nonpositive, and as a consequence D has no focal points (in the sense that any nontrivial Jacobi field along a nontrivial geodesic \(\gamma\) vanishing at \(\gamma\) (0) has ...

Some Finsler spaces with homogeneous geodesics

Mathematische Nachrichten, 2016
A geodesic in a homogeneous Finsler space is called a homogeneous geodesic if it is an orbit of a one‐parameter subgroup of G. A homogeneous Finsler space is called Finsler g.o. space if its all geodesics are homogeneous. Recently, the author studied Finsler g.o. spaces and generalized some geometric results on Riemannian g.o.
