Equivalence between Horndeski and beyond Horndeski theories and imperfect fluids
Israel Quiros, Ulises Nucamendi, Roberto De Arcia +2
In this paper we show that an equivalence between Horndeski and beyond Horndeski theories and general relativity with an effective imperfect fluid can be formally established. The…
An issue with the classification of the scalar-tensor theories of gravity
Israel Quiros, Roberto De Arcia, Ricardo García-Salcedo +2
In the bibliography a certain confusion arises in what regards to the classification of the gravitational theories into scalar-tensor theories and general relativity with a scalar…
Dynamical systems analysis of the cubic galileon beyond the exponential potential and the cosmological analogue of the vDVZ discontinuity
Roberto De Arcia, Tame Gonzalez, Francisco Antonio Horta-Rangel +3
In this paper we generalize the dynamical systems analysis of the cubic galileon model previously investigated in \cite{rtgui} by including self-interaction potentials beyond the e…
Introduction to the application of the dynamical systems theory in the study of the dynamics of cosmological models of dark energy
Ricardo García-Salcedo, Tame Gonzalez, Francisco A. Horta-Rangel +2
The theory of the dynamical systems is a very complex subject which has brought several surprises in the recent past in connection with the theory of chaos and fractals. The applic…
