On contact sub-pseudo-Riemannian isometries
Marek Grochowski, Wojciech Krynski
We study isometries in the contact sub-pseudo-Riemannian geometry. In particular we give an upper bound on the dimension of the isometry group of a general sub-pseudo-Riemannian ma…

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…
