摘要：
The propagation of arbitrary information by electromagnetic and gravitational waves in spatially homogeneous and isotropic cosmological models is examined. The test Maxwellian fields and the gravitational perturbations we study depend upon arbitrary functions in the spirit of Trautman's pioneering analysis. We use the covariant and gauge-invariant approach developed by Ellis and Bruni to study cosmological perturbations under this assumption.
