The EinsteinStraus model consists of a Schwarzschild spherical vacuole in a FriedmanLemâıtreRobertsonWalker (FLRW) dust spacetime (with or without Λ). It constitutes the most widely accepted model to answer the question of the influence of large scale (cosmological) dynamics on local systems. The conclusion drawn by the model is that there is no influence from the cosmic background, since the spherical vacuole is static. Spherical generalizations to other interior matter models are commonly used in the construction of lumpy inhomogeneous cosmological models. On the other hand, the model has proven to be reluctant to admit nonspherical generalizations. In this review, we summarize the known uniqueness results for this model. These seem to indicate that the only reasonable and realistic nonspherical deformations of the EinsteinStraus model require perturbing the FLRW background. We review results about linear perturbations of the EinsteinStraus model, where the perturbations in the vacuole are assumed to be stationary and axially symmetric so as to describe regions (voids in particular) in which the matter has reached an equilibrium regime. 1
