Dynamics and cosmological evolution in Λ-varying cosmology
G. Papagiannopoulos, Pavlina Tsiapi, Spyros Basilakos +1
We study the dynamical properties of a large body of varying vacuum cosmologies for which dark matter interacts with vacuum. In particular, performing the critical point analysis w…
Dynamics of Einstein-Aether Scalar field Cosmology
Andronikos Paliathanasis, G. Papagiannopoulos, Spyros Basilakos +1
We study the cosmological evolution of the field equations in the context of Einstein-Aether cosmology by including a scalar field in a spatially flat Friedmann--Lema\^ıtre--Robert…
Dynamical system analysis at background and perturbation levels: Quintessence in severe disadvantage comparing to CDM
Spyros Basilakos, Genly Leon, G. Papagiannopoulos +1
We perform for the first time a dynamical system analysis of both the background and perturbation equations, of CDM cosmology and quintessence scenario with an exponential poten…
