On the emergence of the [Formula omitted]CDM model from self-interacting Brans-Dicke theory in [Formula omitted]

We investigate whether a self-interacting Brans-Dicke theory in [Formula omitted] without matter and with a time-dependent metric can describe, after dimensional reduction to [Formula omitted], the FLRW model with accelerated expansion and non-relativistic matter. By rewriting the effective 4-dimens...

Description
Summary:We investigate whether a self-interacting Brans-Dicke theory in [Formula omitted] without matter and with a time-dependent metric can describe, after dimensional reduction to [Formula omitted], the FLRW model with accelerated expansion and non-relativistic matter. By rewriting the effective 4-dimensional theory as an autonomous 3-dimensional dynamical system and studying its critical points, we show that the [Formula omitted]CDM cosmology cannot emerge from such a model. This result suggests that a richer structure in [Formula omitted] may be needed to obtain the accelerated expansion as well as the matter content of the 4-dimensional universe.
