Kinetics of small disturbances in an isotropic universe II. Short-wave disturbances in an ultrarelativistic gas

Abstract

Short-wave gravitational disturbances are considered in an isotropic, expanding universe, filled with an ultrarelativistic gas. Solutions are obtained for scalar, vector. and tensor disturbances in the limit nη » 1, where n is the wave vector and n is the time coordinate x4. © 1978 Plenum Publishing Corporation.
