Lorentzian Geometry on the Lobachevsky Plane

Mathematical Notes, 2023
The paper provides descriptions of length maximizing curves, distances, and spheres for left-invariant Lorentzian structures on connected simply connected non-abelian Lie groups of dimension \(2\). Using the Pontryagin maximum principle, the author gives these descriptions in terms of elementary functions.

CR-structures and Lorentzian geometry

Acta Applicandae Mathematicae, 1986
The paper is dealing with interrelations between Cauchy-Riemann structures and Lorentzian geometry. First, the author studies the concept of CR-submanifold [see the reviewer, Geometry of CR-submanifolds (Dordrecht, 1986; Zbl 0605.53001)] in a Lorentz manifold.

CR-Geometry and Shearfree Lorentzian Geometry

Springer Proceedings in Mathematics and Statistics, 2018
We study higher dimensional versions of shearfree null-congurences in conformal Lorentzian manifolds. We show that such structures induce a subconformal structure and a partially integrable almost CR-structure on the leaf space and we classify the Lorentzian metrics that induce the same subconformal structure.
