Locally conformally homogeneous Lorentzian spaces
Thomas Leistner, Lilia Mehidi, Abdelghani Zeghib
We study locally conformally homogeneous Lorentzian manifolds of dimension at least , admitting an essential pseudo-group of local conformal transformations. Generalizing a rece…
Conformal Killing tensors and their Killing scales
A. Rod Gover, Jonathan Kress, Thomas Leistner
We address the problem of how to characterise when a rank-two conformal Killing tensor is the trace-free part of a Killing tensor for a metric in the conformal class. We call such…
Lorentzian homogeneous structures with indecomposable holonomy
Steven Greenwood, Thomas Leistner
For a Lorentzian homogeneous space, we study how algebraic conditions on the isotropy group affect the geometry and curvature of the homogeneous space. More specifically, we prove…
Killing vector fields on semi-Riemannian product manifolds
Federico Costanza, Thomas Leistner
Hano's theorem states that the space of Killing vector fields of a complete simply connected Riemannian manifold is isomorphic to the direct sum of the Killing vector fields of the…
Completeness of certain compact Lorentzian locally symmetric spaces
Thomas Leistner, Thomas Munn
We show that a compact Lorentzian locally symmetric space is geodesically complete if the Lorentzian factor in the local de Rham-Wu decomposition is of Cahen-Wallach type or if the…
