Popis:	In order to facilitate study of the difference between asymptotically flat and nonasymptotically flat boundary conditions on “Machian effects,” I study a rotating shell of perfect fluid separating a Minkowski interior from a closed Friedman-Robertson-Walker exterior. The shell is comoving with the dust in the exterior region, therefore it is observed to be expanding or collapsing relative to the Minkowski interior. Treating the rotation as a firstorder perturbation, I derive the time and spatial dependence of a given rotational perturbation and how it compares to analogous computations for asymptotically flat configurations. An extension of Bardeen's definition of the locally nonrotating observer is proposed for this nonstationary situation.
