Optical reference geometry and inertial forces in Kerr-de Sitter spacetimes |
Abstract _ |
The optical reference geometry enables to introduce the concept of inertial forces which provides a description of relativistic dynamics in accord with 'Newtonian' intuition, whereas properties of the optical geometry and inertial forces reflects some hidden features of spacetimes. We discuss behaviour of the forces in the Kerr-de Sitter spacetimes and their limit cases, representing in this way the influence of the rotational and cosmological parameters on the particle motion. Obtained results are illustrated by embedding diagrams of the optical geometry, closely related to the behaviour of the centrifugal force. |
