We study a generalized non-local theory of gravity which, in specific limits, can become either the curvature non-local or teleparallel non-local theory. Using the Noether symmetry approach, we find that the coupling functions coming from the non-local terms are constrained to be either exponential or linear in form. It is well known that in some non-local theories, a certain kind of exponential non-local couplings is needed in order to achieve a renormalizable theory. In this paper, we…

De Sitter and power-law solutions in non-local Gauss–Bonnet gravity

The cosmological dynamics of a non-locally corrected gravity theory, involving a power of the inverse d’Alembertian, is investigated. Casting the dynamical equations into local form, the fixed points

Non-local curvature and Gauss–Bonnet cosmologies by Noether symmetries

Non-local gravity cosmologies are considered under the standard of Noether symmetry approach. In particular, we focus on non-local theories whose gravitational actions depend on curvature and

Phase space description of nonlocal teleparallel gravity

We study cosmological solutions in nonlocal teleparallel gravity or f(T) theory, where T is the torsion scalar in teleparallel gravity. This is a natural extension of the usual teleparallel gravity

Exact Spherically Symmetric Solutions in Modified Gauss-Bonnet Gravity from Noether Symmetry Approach

Ten different forms of f are found that present symmetries and calculate their invariant quantities, i.e., Noether vector fields, which are used to find exact spherically symmetric solutions in some of the models of f ( R, G ) theory.

All degrees of freedom related to the torsion scalar can be explored by analysing, the f ( T, T G ) gravity formalism where, T is a torsion scalar and T G is the teleparallel counterpart of the

Modified teleparallel theories of gravity

Teleparallel gravity is an alternative formulation of gravity which has the same field equations as General Relativity (GR), therefore, it also known as the Teleparallel equivalent of General

Revival of the Deser-Woodard nonlocal gravity model: Comparison of the original nonlocal form and a localized formulation

We examine the origin of two opposite results for the growth of perturbations in the Deser-Woodard (DW) nonlocal gravity model. One group previously analyzed the model in its original nonlocal form

Invariant solutions and Noether symmetries in Hybrid Gravity

Symmetries play a crucial role in physics and, in particular, the Noether symmetries are a useful tool both to select models motivated at a fundamental level, and to find exact solutions for specific
