# Massless fields in scalar-tensor cosmologies.

PHYSICAL REVIEW D, no. 2 (1995): 477-489

WOS

We derive exact Friedmann--Robertson--Walker cosmological solutions in general scalar--tensor gravity theories, including Brans--Dicke gravity, for stiff matter or radiation. These correspond to the long or short wavelength modes respectively of massless scalar fields. If present, the long wavelength modes of such fields would be expected...更多
