The twistor equation in Lorentzian spin geometry
Helga Baum, Felipe Leitner
In this paper we discuss the twistor equation in Lorentzian spin geometry. In particular, we explain the local conformal structure of Lorentzian manifolds, which admit twistor spin…

Imaginary Killing Spinors in Lorenztian Geometry
Felipe Leitner
We study the geometric structure of Lorentzian spin manifolds, which admit imaginary Killing spinors. The discussion is based on the cone construction and a normal form classificat…
