Lorentzian twistor spinors and CR-geometry

Helga Baum

We prove that there exist global solutions of the twistor equation on the Fefferman spaces of strictly pseudoconvex spin manifolds of arbitrary dimension and we study their propert…

Twistor spinors on Lorentzian symmetric spaces

Helga Baum

We solve the twistor equation on all indecomposable Lorentzian symmetric spaces explicity.

Parallel spinors and holonomy groups on pseudo-Riemannian spinmanifolds

Helga Baum, Ines Kath

We describe the possible holonomy groups of simply connected irreducible non-locally symmetric pseudo-Riemannian spin manifolds which admit parallel spinors.
