M. Gedalin et Db. Melrose, Waves in strongly magnetized relativistic plasmas: Generally covariant approach - art. no. 027401, PHYS REV E, 6402(2), 2001, pp. 7401
A dispersion relation for long waves in strongly magnetized multifluid plas
ma in a curved spacetime is derived in a covariant form. A generally covari
ant form for the ray equations is obtained. The results are applicable to r
ay propagation in relativistic plasmas in the vicinity of strongly gravitat
ing (black holes) or rapidly rotating (pulsars) systems.
