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.
