On Sectional Curvature Operator of 3-dimensional Locally Homogeneous Lorentzian Manifolds
O. P. Khromova, S. V. Klepikova, E. D. Rodionov
The main purpose of this paper is to determine the admissible forms of the sectional curvature operator on a three-dimensional locally homogeneous Lorentzian manifolds.
About the Schouten-Weyl tensor on 3-dimensional Lorenzian Lie groups
O. P. Khromova, P. N. Klepikov, S. V. Klepikova +1
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 m…
Left-invariant pseudo-Riemannian metrics on four-dimensional Lie groups with zero Schouten-Weyl tensor
Olesya P. Khromova, Pavel N. Klepikov, Eugene D. Rodionov
In the presented paper left-invariant pseudo-Riemannian metrics on four-dimensional Lie groups with zero Schouten-Weyl tensor are investigated. The complete classification of these…
