A new approach in stability analysis: case study: tachyon cosmology with non-minimally coupled scalar field-matter
H. Farajollahi, A. Salehi
We study the general properties of attractors in a cosmological model with tachyonic potential and a scalar field non-minimally coupled to matter. A general analytic formulation is…
Stability analysis in Modified Non-Local Gravity
H. Farajollahi, F. Milani
In this paper we consider FRW cosmology in modified non-local gravity. The stability analysis shows that there is only one stable critical point for the model and the universe unde…
Attractors, Statefinders and Observational Measurement for Chameleonic Brans--Dicke Cosmology
Hossein Farajollahi, Amin Salehi
We investigate chameleonic Brans--Dicke model applied to the FRW universes. A framework to study stability and attractor solutions in the phase space is developed for the model. We…
On Dynamics of Brans--Dicke Theory of Gravitation
Hossein Farajollahi, Mehrdad Farhoudi, Hossein Shojaie
We study longstanding problem of cosmological clock in the context of Brans-Dicke theory of gravitation. We present the Hamiltonian formulation of the theory for a class of spatial…
A 5D noncompact Kaluza -Klein cosmology in the presence of Null perfect fluid
H. Farajollahi, H. Amiri
For the description of the early inflation, and acceleration expansion of the Universe, compatible with observational data, the 5D noncompact Kaluza--Klein cosmology is investigate…
