Massless fields in scalar-tensor cosmologies.
PHYSICAL REVIEW D, no. 2 (1995): 477-489
WOS
摘要
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
