Review on exact and perturbative deformations of the Einstein-Straus model : un...
Mena, Filipe C.; Mars, Marc; Vera, RaulThe Einstein-Straus model consists of a Schwarzschild spherical vacuole in a Friedman-Lema^ tre-Robertson-Walker (FLRW) dust spacetime (with or without ). It constitutes the most widely accepted model to answer the question of the in uence of large scale (cosmological) dynamics on local systems. The conclusion drawn by the model is that there is no in uence from the cosmic background, since the spher- ical vac...

An application of the SIR model to the evolution of epidemics in Portugal
