Asymptotically Plane Wave Spacetimes and their Actions

Witt, Julian Le, Ross, Simon F.

Understand

We propose a definition of asymptotically plane wave spacetimes in vacuum gravity in terms of the asymptotic falloff of the metric, and discuss the relation to previously constructed exact solutions.

  • We construct a well-behaved action principle for such spacetimes, using the formalism developed by Mann and Marolf.
  • We show that this action is finite on-shell and that the variational principle is well-defined for solutions of vacuum gravity satisfying our asymptotically plane wave falloff conditions.
