Light propagation and the average expansion rate in near-FRW universes
Light propagation average expansion rate universes
2011/9/29
We consider universes which are close to Friedmann-Robertson-Walker in the sense that metric perturbations, their time derivatives and first spatial derivatives are small, but second spatial derivativ...
