Peeling of Dirac field on Kerr spacetime

Abstract

We investigate to construct a conformal scattering theory of the spin-1/2 massless Dirac equation on the Kerr spacetime by using the conformal geometric method and under an assumption on the pointwise decay of the Dirac field. In particular, our construction is valid in the exteriors of Schwarzschild and very slowly Kerr black hole spacetimes, where the pointwise decay was established.
