3-dimensional left-invariant sub-Lorentzian contact structures
Marek Grochowski, Alexandr Medvedev, Ben Warhurst
We provide a classification of -invariant sub-Lorentzian structures on dimensional contact Lie groups. Our approach is based on invariants arising form the construction of…

Invariants of contact sub-pseudo-Riemannian structures and Einstein-Weyl geometry
Marek Grochowski, Wojciech Krynski
We consider local geometry of sub-pseudo-Riemannian structures on contact manifolds. We construct fundamental invariants of the structures and show that the structures give rise to…
