On the relation between tensor and scalar perturbation modes in Friedmann cosmology

Abstract

An elementary derivation of the fundamental relation $T/S=4\gamma$ between the tensor and scalar modes of cosmological perturbations in the early universe is given. Statements by L.P.Grishchuk on this problem are commented on.
