Twistor spinors on Lorentzian manifolds, CR-geometry and Fefferman spaces

Helga Baum


Abstract. The paper deals with twistor spinors on Lorentzian manifolds. In particular, we explain a relation between a certain class of Lorentzian twistor spinors and the Fefferman spaces of strictly pseudoconvex spin manifolds which appear in CR-geometry.
