On the structure of -step nilpotent Lorentzian naturally reductive Lie groups
Brian Luporini, Silvio Reggiani, Francisco Vittone
We study -step nilpotent Lie groups with naturally reductive left-invariant Lorentzian metrics with respect to the presentation group . Replaci…

The distribution of symmetry of Lorentzian naturally reductive nilmanifolds
Brian Luporini, Silvio Reggiani, Francisco Vittone
We study -step nilpotent Lorentzian Lie groups , which are naturally reductive with respect to a certain class of transitive subgroups of isometries. We describe the isotropy…
