The Dirac propagator in the extreme Kerr metric
D. Batic, H. Schmid
Starting with the Dirac equation in the extreme Kerr metric we derive an integral representation for the propagator of solutions of the Cauchy problem with initial data in the clas…

Heun equation, Teukolsky equation, and type-D metrics
D. Batic, H. Schmid
Starting with the whole class of type-D vacuum backgrounds with cosmological constant we show that the separated Teukolsky equation for zero rest-mass fields with spin (g…
