Homogeneous Geodesics in Homogeneous Affine Manifolds

Results in Mathematics, 2009
For studying homogeneous geodesics in Riemannian and pseudo-Riemannian geometry (on reductive homogeneous spaces) there is a simple algebraic formula which involves the reductive decomposition \(\mathfrak{g} = \mathfrak{h} + \mathfrak{m}\) of the Lie algebra \(\mathfrak{g}\) of the isometry group G and the scalar product on \(\mathfrak{m}\) induced by ...

Homogeneous Lorentzian Spaces Whose Null-geodesics are Canonically Homogeneous

Letters in Mathematical Physics, 2006
A homogeneous Lorentzian space is said to be a null geodesic orbit-space, if all null geodesics are homogeneous. The aim of this paper is to show that the null geodesic orbit-spaces for which all geodesic vectors are canonical admit a non-vanishing homogeneous Lorentzian structure belonging to the class \(T_1\oplus T_3\).
