Falsifying cosmological models based on a non-linear electrodynamics
Ali Övgün, Genly Leon, Juan Magaña +1
Recently, the nonlinear electrodynamics (NED) has been gaining attention to generate primordial magnetic fields in the Universe and also to resolve singularity problems. Moreover,…
Cartan symmetries and global dynamical systems analysis in a higher-order modified teleparallel theory
L. Karpathopoulos, S. Basilakos, G. Leon +2
In a higher-order modified teleparallel theory cosmological we present analytical cosmological solutions. In particular we determine forms of the unknown potential which drives the…
Non-minimally coupled scalar field cosmology with torsion
Antonella Cid, Fernando Izaurieta, Genly Leon +2
In this work we present a generalized Brans-Dicke lagrangian including a non-minimally coupled Gauss-Bonnet term without imposing the vanishing torsion condition. In the resulting…
Noether symmetries and stability of ideal gas solution in Galileon Cosmology
N. Dimakis, Alex Giacomini, Sameerah Jamal +2
A class of generalized Galileon cosmological models, which can be described by a point-like Lagrangian, is considered in order to utilize Noether's Theorem to determine conservatio…
Dynamical Analysis of an Integrable Cubic Galileon Cosmological Model
Alex Giacomini, Sameerah Jamal, Genly Leon +2
Recently a cubic Galileon cosmological model was derived by the assumption that the field equations are invariant under the action of point transformations. The cubic Galileon mode…
Global structure of static spherically symmetric solutions surrounded by quintessence
Miguel Cruz, Apratim Ganguly, Radouane Gannouji +2
We investigate all static spherically symmetric solutions in the context of general relativity surrounded by a minimally-coupled quintessence field, using dynamical system analysis…
