Quintom cosmologies with arbitrary potentials
Ruth Lazkoz, Genly León, Israel Quiros
In this paper we investigate quintom cosmologies with arbitrary potentials from the dynamical systems perspective. The dynamical systems analysis is complete in the sense that it i…

Quintom cosmologies admitting either tracking or phantom attractors
Ruth Lazkoz, Genly León
In this paper we investigate the evolution of a class of cosmologies fuelled by quintom dark energy and dark matter. Quintom dark energy is a hybrid of quintessence and phantom whi…

Interacting Phantom Energy and Avoidance of the Big Rip Singularity
Ruben Curbelo, Tame Gonzalez, Genly León +1
Models of the universe with arbitrary (non gravitational) interaction between the components of the cosmic fluid: the phantom energy and the background, are investigated. A general…
