Black-hole lattices — •Eloisa Bentivegna1 and Mikolaj Korzynski2 — 1Max Planck Institute for Gravitational Physics — 2Center for Theoretical Physics at the Polish Academy of Sciences
Regular black-hole lattices have recently been proposed as a testbed to investigate the role of small-scale inhomogeneities in spaces that are homogeneous on larger scales. I will present a brief history of the developments in this area and then discuss the construction of black-hole lattices in two cases, characterized by whether the corresponding spacetime contains a time-symmetric spatial hypersurface. Finally, I will illustrate the cosmological relevance of these models by comparing them to the zero-pressure Friedmann-Lemaître-Robertson-Walker class.
