Lorentzian Metrics Null-Projectively Related to Semi-Riemannian Metrics
Olea-Andrades, Benjamín
; Palomo-Ruiz, Francisco José (Springer Nature, 2022-12-19)
We say that a Lorentzian metric and a semi-Riemannian metric on the same manifold M are null-projectively related if every null geodesic of the Lorentzian metric is an unparametrized geodesic of the semi-Riemannian one. ... -
Mean curvature of spacelike submanifolds in a Brinkmann spacetime
Several geometric properties of complete spacelike submanifolds, with codimension at least two, in a Brinkmann spacetime are shown from natural assumptions involving the mean curvature vector field $\mcv$ of the spacelike ... -
Rigidity results for complete spacelike submanifolds in plane fronted waves
Palomo-Ruiz, Francisco José; Pelegrín, José A. S.; Romero, Alfonso (Springer, 2022-09-08)
New rigidity results for complete non-compact spacelike submanifolds of arbitrary codimension in plane fronted waves are obtained. Under appropriate assumptions, we prove that a complete spacelike submanifold in these ...
