Abstract
Some black hole-cosmic string models such as Reissner-Nordström, RN-de Sitter, Kerr-Newman and multi-black holes with cosmic string are given. Energy and angular momentum of a, timelike particle in circular orbits in multi-black hole space-time are calculated. The geodesic equations for the timelike particles for the far region of the multi-black hole sources are calculated and small oscillations around the circular orbit obtained. It is seen that the particle's orbit precesses like the Lens-Thirring effect.
