Abstract:
We present results of our recent studies concerning effects of Λ
> 0 in astrophysically motivated problems. Here we summarize
properties of circular geodesic motion of test particles in the
equatorial plane of Kerr-de Sitter black-hole and naked-singularity
spacetimes. Along with the standard analysis of geodesic equations of
the ordinary geometry, we introduce alternative inertial forces
formalism defined within the General Theory of Relativity in the
framework of optical reference geometry.
