THE ENERGY LOCALIZATION PROBLEM AND THE RENORMALIZED VACUUM ENERGY IN STATIC ROBERTSON-WALKER UNIVERSES

BAYM, SS
We calculate the renormalized quantum vacuum energy inside a spherical boundary for the massless conformal scalar field in curved background Robertson-Walker geometry. We use the mode sum method with an exponential cuttoff. In our calculations we do not make assumptions about the exterior geometry or the global topology of the universe.
