Classical and quantum solutions in Brans-Dicke cosmology with a perfect fluid
(American Physical SocietyPhysical Review D, 2016)We consider the application of group invariant transformations in order to constrain a flat isotropic and homogeneous cosmological model, containing of a Brans-Dicke scalar field and a perfect fluid with a constant equation ...

Dynamical symmetries in Brans-Dicke cosmology
(American Physical SocietyPhysical Review D, 2017-01-20)In the context of generalized Brans-Dicke cosmology we use the Killing tensors of the minisuperspace in order to determine the unspecified potential of a scalar-tensor gravity theory. Specifically, based on the existence ...
