New exact cosmological solutions to Brans-Dicke gravity with a self-interacting scalar-field
Olga Arias, Israel Quiros
We derive a new parametric class of exact cosmological solutions to Brans-Dicke theory of gravity with a self-interacting scalar field and a barotropic perfect fluid of ordinary ma…

New exact cosmological solutions to Einstein's gravity minimally coupled to a Quintessence field
Olga Arias, Tame Gonzalez, Israel Quiros
A linear relationship between the Hubble expansion parameter and the time derivative of the scalar field is assumed in order to derive exact analytic cosmological solutions to Eins…
