Abstract:A generalized Brans-Dicke theory of gravitation is applied to investigate a cosmological model for primordial 
 universe that includes a self-interacting bosonic field as source. This model permits, initially, to consider an arbitrary $\omega$ function, not usual for BD formulations. The imposition of Noether symmetries conditions identifies a reduced space for the $\omega$ function. This model is shown to present a variety of behaviors consistent with a primordial era, de… Show more
