N2  - Both circular and epicyclic motion of test particles along equatorial circular orbits in the revisited Kerrde Sitter spacetime are analyzed. We present relations for specific energy, specific angular momentum, and Keplerian angular velocity of particles on equatorial circular orbits, and discuss criteria for the existence and stability of such orbits giving limits on spacetime parameters. Finally, we discuss the epicyclic motion along equatorial circular orbits obtaining relations for radial and vertical epicyclic frequencies. The results are compared with those for standard Kerr-de Sitter geometry.
