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.
