Abstract:
The possibility of constructing an Einstein-Strauss-de Sitter model of
the Universe (i.e. a model of Schwarzschild-de Sitter mass condensations
immersed in a Friedmann universe with the cosmological constant Λ
present) is proved. Geodesic motion is considered in both the
Schwarzschild-de Sitter and Friedmann parts of the model, and the
matching of geodesics across the matching hypersurface of these parts is
given. Some consequences of this geodesics-matching, which should be
relevant in the process of formation and evolution of mass condensations
due to gravitational instability of massive neutrinos in a
neutrino-dominated universe, are discussed.
