We investigate the main features of the flat Friedmann-Lemaître-Robertson-Walker
cosmological<? format?> models in the f (T) modified gravity regime. In particular, a general …

As is well known, symmetry plays an important role in the theoretical physics. In particular,
the well-known Noether symmetry is an useful tool to select models motivated at a …

The field equations following from a Lagrangian L (R) will be deduced and solved for special
cases. If L is a non-linear function of the curvature scalar, then these equations are of fourth …

We consider the two scalar field cosmology in a Friedmann Robertson Walker spatially flat
spacetime where the scalar fields interact both in the kinetic part and the potential. We apply …

We consider the Noether symmetry approach to find exact cosmological solutions in f (T)-
gravity. Instead of taking into account phenomenological models, we apply the Noether …

In this Letter by utilizing the Noether symmetry approach in cosmology, we attempt to find the
tachyon potential via the application of this kind of symmetry to a flat Friedmann–Robertson …

This volume summarizes the many alternatives and extensions to Einstein's General Theory
of Relativity, and shows how symmetry principles can be applied to identify physically viable …

The Noether symmetry of a generic f (R) cosmological model is investigated by utilizing the
behavior of the corresponding Lagrangian under the infinitesimal generators of the desired …

In the framework of scalar-tensor gravity, we consider non-flat interacting quintessence
cosmology where a scalar field is interacting with dark matter. Such a scalar field can be a …

We perform a detailed study of the modified gravity f (R) models in the light of the basic
geometrical symmetries, namely Lie and Noether point symmetries, which serve to illustrate …
