Abstract:
In this note we prove that the Heisenberg group with a left-invariant pseudo-Riemannian metric admits a completely integrable totally geodesic distribution of codimension 1. This is on the contrary to the Riemannian case, as it was proved by T. Hangan.
Keywords:
Heisenberg group; pseudo-Riemannian metrics; geodesics; codimension 1 distributions.
