Geodesic completeness of some Lorentzian simple Lie groups
E. Ebrahimi, S. M. B. Kashani, M. J. Vanaei
In this paper we investigate geodesic completeness of left-invariant Lorentzian metrics on a simple Lie group when there exists a left-invariant Killing vector field on …
Semi-Riemannian hypersurfaces in with a totally geodesic foliation of codimension one
S. M. B. Kashani, M. J. Vanaei, S. M. Yaghoobi
We classify hypersurfaces of the Minkowski space that carry a totally geodesic foliation with complete leaves of codimension one. We prove that such a hypersurface is rul…
Real hypersurfaces in with commuting structure Jacobi operator
N. Heidari, S. M. B. Kashani, M. J. Vanaei
In this paper we study real hypersurfaces in the complex quadric space whose structure Jacobi operator commutes with their structure tensor field. We show that the Reeb curva…
Cohomogeneity one actions on anti de Sitter spacetimes
J. C. Diaz-Ramos, S. M. B. Kashani, M. J. Vanaei
In this paper we classify, up to orbit equivalence, cohomogeneity one actions of connected closed Lie subgroups of on the -dimensional anti de Sitter spacetime $Ad…
Hypersurfaces in space forms satisfying the condition
Luis J. Alias, S. M. B. Kashani
We study hypersurfaces either in the sphere \s{n+1} or in the hyperbolic space \h{n+1} whose position vector satisfies the condition , where is the linearized…
