Normal modes for metric fluctuations in a class of anisotropic backgrounds
We relax the assumption of isotropy of the background manifold in the gauge invariant approach to the theory of cosmological perturbations. We find the normal modes which diagonalize the perturbed action, for a scalar field minimally coupled to gravity in a manifold {\cal M} of the Bianchi-type I, u...
