Friction Forces in General Relativity
Abstract
Friction forces play an important role in a wide class of phenomena both in the contexts of classical mechanics and general relativity. This paper discusses the Poynting-Robertson approach to the description of the motion of a massive test particle inside a perfect fluid undergoing dissipative effects in curved space. Specific cases of motions 1) inside a photon gas near a Schwarzschild black hole; 2) inside a photon gas in the Tolman metric are then discussed with applications to models of accretion disks of a black hole and to motion inside a static radiation dominated Universe.
