چکیده

All degrees of freedom related to the torsion scalar can be explored by analysing, $f(T,T_G)$ gravity formalism where, $T$ is a and $T_G$ teleparallel counterpart Gauss-Bonnet topological invariant term. The well-known Noether symmetry approach useful tool for selecting models that are motivated at fundamental level determining exact solution given Lagrangian, hence we explore in with three different forms study how establish nontrivial vector form each one them. We extend analysis made \cite{capozziello2016noether} $f(T,T_{G})=b_{0}T_{G}^{k}+t_{0}T^{m}$ discussed this model linear equivalent term, followed two containing exponential have shown all cases will allow us obtain non-trivial which play an important role solutions cosmological equations.

Noether symmetries in Gauss–Bonnet-teleparallel cosmology

A generalized teleparallel cosmological model, [Formula: see text], containing the torsion scalar T and the teleparallel counterpart of the Gauss-Bonnet topological invariant [Formula: see text], is studied in the framework of the Noether symmetry approach. As [Formula: see text] gravity, where [Formula: see text] is the Gauss-Bonnet topological invariant and R is the Ricci curvature scalar, ex...

Constraining generalized non-local cosmology from Noether symmetries

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 exponentia...

Noether symmetry approach in f(T, B) teleparallel cosmology

We consider the cosmology derived from f(T, B) gravity where T is the torsion scalar and [Formula: see text] a boundary term. In particular we discuss how it is possible to recover, under the same standard, the teleparallel f(T) gravity, the curvature f(R) gravity, and the teleparallel-curvature f(R, T) gravity, which are particular cases of f(T, B). We adopt the Noether Symmetry Approach to st...

Noether Theorem for Μ-symmetries

We give a version of Noether theorem adapted to the framework of μ-symmetries; this extends to such case recent work by Muriel, Romero and Olver in the framework of λ-symmetries, and connects μ-symmetries of a Lagrangian to a suitably modified conservation law. In some cases this “μconservation law” actually reduces to a standard one; we also note a relation between μ-symmetries and conditional...
