title = "CR-Geometry and Shearfree Lorentzian Geometry",
abstract = "We study higher dimensional versions of shearfree null-congruences 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. In the last section we survey some known applications of the correspondence between almost CR-structures and shearfree null-congruences in dimension 4.",
