On Killing vectors in initial value problems for asymptotically flat space-times
arXiv:gr-qc/0007009 · doi:10.1088/0264-9381/17/24/303
Abstract
The existence of symmetries in asymptotically flat space-times are studied from the point of view of initial value problems. General necessary and sufficient (implicit) conditions are given for the existence of Killing vector fields in the asymptotic characteristic and in the hyperboloidal initial value problem (both of them are formulated on the conformally compactified space-time manifold).
