Dynamical system analysis of Myrzakulov gravity
G. Papagiannopoulos, Spyros Basilakos, Emmanuel N. Saridakis
We perform a dynamical system analysis of Myrzakulov or F(R, T) gravity, which is a subclass of affinely connected metric theories, where ones uses a specific but non-special conne…
Dynamics in Varying vacuum Finsler-Randers Cosmology
G. Papagiannopoulos, S. Basilakos, A. Paliathanasis +2
In the context of Finsler-Randers theory we consider, for a first time, the cosmological scenario of the varying vacuum. In particular, we assume the existence of a cosmological fl…
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…
Cosmological singularities and analytical solutions in varying vacuum cosmologies
S. Basilakos, A. Paliathanasis, J. D. Barrow +1
We investigate the dynamical features of a large family of running vacuum cosmologies for which evolves as a polynomial in the Hubble parameter. Specifically, using the critica…
New integrable models and analytical solutions in ~cosmology with an ideal gas
G. Papagiannopoulos, Spyros Basilakos, John D. Barrow +1
In the context of -gravity with a spatially flat FLRW metric containing an ideal fluid, we use the method of invariant transformations to specify families of mod…
Finsler-Randers Cosmology: dynamical analysis and growth of matter perturbations
G. Papagiannopoulos, S. Basilakos, A. Paliathanasis +2
We study for the first time the dynamical properties and the growth index of linear matter perturbations of the Finsler-Randers (FR) cosmological model, for which we consider that…
Dynamical symmetries in Brans-Dicke cosmology
G. Papagiannopoulos, John D. Barrow, S. Basilakos +2
In the context of generalised Brans-Dicke cosmology we use the Killing tensors of the minisuperspace in order to determine the unspecified potential of a scalar-tensor gravity theo…
