Gravitoelectromagnetism

http://arxiv.org/abs/gr-qc/0011014Gravitoelectromagnetism is briefly reviewed and some recent developments in this topic are discussed. The stress-energy content of the gravitoelectromagnetic field is described from different standpoints. In particular, the gravitational Poynting flux is analyzed and it is shown that there exists a steady flow of gravitational energy circulating around a rotating mass.I would like to thank the organizers of the Spanish RelativityMeeting (EREs2000) for their kind invitation and warm hospitality
