Shielding linearised gravity
arXiv:1701.00486 · doi:10.1103/PhysRevD.95.064063
Abstract
We present an elementary argument that one can shield linearised gravitational fields using linearised gravitational fields. This is done by using third-order potentials for the metric, which avoids the need to solve singular equations in shielding or gluing constructions for the linearised metric.
