The space spinor formalism and estimates for spinor fields
Mariem Magdy, Juan A. Valiente Kroon
We show how the space spinor formalism for 2-component spinors can be used to construct estimates for spinor fields satisfying first order equations. We discuss the connection of t…

An asymptotic characterisation of the Kerr spacetime
Robert Sansom, Juan A. Valiente Kroon
We provide a characterisation of the Kerr spacetime close to future null infinity using the asymptotic characteristic initial value problem in a conformally compactified spacetime.…
