About the Schouten-Weyl tensor on 3-dimensional Lorenzian Lie groups

Autor: Khromova, O. P., Klepikov, P. N., Klepikova, S. V., Rodionov, E. D.

The main purpose of this paper is to investigate the Schouten-Weyl tensor on the three-dimensional Lie groups with left-invariant Lorenzian metrics. The left-invariant Lorentzian metrics on the three-dimensional Lie groups with squared length zero Sc
