Starting from an anisotropic flat cosmological model (Bianchi type I), we show that conditions leading to isotropization fall into three classes, respectively 1, 2 and 3. We look for necessary conditions such that a Bianchi type I model reaches a stable isotropic state due to the presence of several massive scalar fields minimally coupled to the metric with a perfect fluid for class 1 isotropization. The conditions are written in terms of some functions l of the scalar fields. Two types of… 
Energy exchange for homogeneous and isotropic universes with a scalar field coupled to matter
We study the late time evolution of flat and negatively curved Friedmann?Robertson?Walker (FRW) models with a perfect fluid matter source and a scalar field arising in the conformal frame of f(R)
Coupled quintessence with double exponential potentials
We study flat Friedmann-Robertson-Walker (FRW) models with a perfect fluid matter source and a scalar field non minimally coupled to matter having a double exponential potential. It is shown that the
Isotropisation of flat homogeneous Bianchi type I model with a non minimally coupled and massive scalar field
In previous works, we studied the isotropisation of some Bianchi class A models with a minimally coupled scalar field. In this paper we extend these results, in the special case of a Bianchi type I
Stochastic Eternal Inflation in a Bianchi Type I Universe
The phenomenon of stochastic eternal inflation is studied for a chaotic inflation potential in a Bianchi Type I spacetime background. After deriving the appropriate stochastic Klein-Gordon equation,

Isotropization of generalized scalar-tensor theory plus a massive scalar field in the Bianchi type I model
In this paper we study the isotropization of a generalized scalar-tensor theory with a massive scalar field. We find it depends on a condition on the Brans-Dicke coupling function and the potential,

Density perturbations and black hole formation in hybrid inflation.
TLDR
It is shown that density perturbations in hybrid inflation models of the new type can be very large on the scale corresponding to the phase transition, which could lead to a copious production of black holes in these models.
Isotropization of the minimally coupled scalar–tensor theory with a massive scalar field and a perfect fluid in the Bianchi type I model
We look for necessary conditions such that the minimally coupled scalar–tensor theory with a massive scalar field and a perfect fluid in the Bianchi type I model isotropizes. We then derive the

We examine the late-time behavior of intially expanding homogeneous cosmological models satisfying Einstein's equation with a positive cosmological constant $\ensuremath{\Lambda}$. It is shown that
Extended gravity theories and the Einstein--Hilbert action
I discuss the relation between arbitrarily high-order theories of gravity and scalar--tensor gravity at the level of the field equations and the action. I show that (2n+4)-order gravity is
