General relativity limit of the scalar-tensor theories for traceless matter field
Abstract
Description
$ω(ϕ) \to \infty$ limit of scalar tensor theories are studied for traceless matter source. It is shown that the limit $ω(ϕ) \to \infty$ does not reduce a scalar tensor theory to general relativity.
An exact radiation solution of scalar tensor cosmology under Nordtvedt conditions is obtained for flat Friedmann universe.
