Euclidean Friedman–Robertson–Walker cosmology in Brans–Dicke-like theories of gravity

An explicit and tractable form of the complete solution of Brans–Dicke Euclidean Friedman–Robertson–Walker cosmology, in the matter dominated area, is proposed. In this derivation, the (generally imposed) constraint on the Brans–Dicke parameter ω>−3/2 is relaxed. An isolated power-law solution is exhibited, which turns out to describe an accelerated expansion of the universe, without recourse to any cosmological constant or quintessence matter. It appears that this solution can be generalized for all Brans–Dicke-like theories of gravity.
