Abstract
We present a systematic treatment of the linear theory of scalar gravitatio nal perturbations of various matter (including baryons, cold dark matter, p hotons, massless neutrinos, and massive neutrino) for the flat, open and cl ose universes, concentrating on the treatment of the massive neutrino compo nent which has been either ignored or approximated crudely for the nonflat universe in previous literatures.
