Exact Scaling Solutions in Normal and Brans-Dicke Models of Dark Energy
Olga Arias, Tame Gonzalez, Yoelsy Leyva +1
A linear relationship between the Hubble expansion parameter and the time derivative of the scalar field is explored in order to derive exact cosmological, attractor-like solutions…
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…
Thick Brane Worlds Arising From Pure Geometry
Olga Arias, Rolando Cardenas, Israel Quiros
We study a non-Riemannian modification of 5-dimensional Kaluza-Klein theory. In our proposal the Riemannian structure of the five-dimensional manifold is replaced by a Weyl-integra…
