We study the phase space of the quintom cosmologies for a class of exponential potentials.
We combine normal forms expansions and the center manifold theory in order to describe …

In this paper we derive a novel cosmological model from the f (R, T) theory of gravitation, for
which R is the Ricci scalar and T is the trace of the energy‐momentum tensor. We consider …

In this paper, the model of interaction is studied between f (T, T) gravity and modified
Chaplygin gas in Friedmann–Robertson–Walker (FRW)-flat metric. We obtain the Friedmann …

In this work we have studied a cosmological model based on a quintom dark energy model
non-minimally coupled with gravity, endowed with a specific potential energy of the …

In this work we propose a novel dark energy model in the formalism of quintom scenarios in
scalar-tensor theories based on general relativity, taking into account generalized couplings …

In this paper, we report the existence of transitioning scenario of Bianchi type I universe in
the context of f (R, T) gravity with special case f (R, T)= f 1 (R)+ f 2 (R) f 3 (T) and its functional …

We study Noether symmetries of a class of non-minimally coupled scalar field in a
background spatially flat Friedmann-Robertson-Walker (FRW) spacetime. We explore the …

In this work, we propose a new dark energy cosmological model, by considering a new
quintom scenario which is based on the superposition between a quintessence scalar field …

We present a novel way to constrain the ghost field with respect to other physical fields
present in a given theory such that the theory becomes quantizable. This is achieved by …

In this work we have considered a quintom cosmological model with generalised Galileon
corrections in the scalar tensor theories of gravitation. After proposing the corresponding …
