Abstract:
The role of a nonzero cosmological constant is discussed for black-hole
or naked-singularity spacetimes, Einstein-Strauss vacuola spacetimes,
and general relativistic polytropic fluid spheres. In case of the
black-hole spacetimes, motion of test particles and photons and
equilibrium configurations of test perfect fluid are considered. Their
relevance to astrophysically very important accretion processes in disk
regime is established.
