Asymptotic charges of a quadrupolar naked singularity
Edgar Gasperin, Mariem Magdy
The purpose of this article is to compute the asymptotic charges of a vacuum solution to the Einstein field equations describing a naked singularity with a non-vanishing quadrupole…

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…

Asymptotics of spin-0 fields and conserved charges on n-dimensional Minkowski spaces
Edgar GasperÃn, Mariem Magdy, Filipe C. Mena
We use conformal geometry methods and the construction of Friedrich's cylinder at spatial infinity to study the propagation of spin- fields (solutions to the wave equation) on $…
