چکیده

Statefinder diagnostic is a convenient method that can differentiate between the various dark energy models. In this article, we analyze statefinder parameters in symmetric teleparallel cosmology. The $f(Q)$ gravity theory an alternative to GR, where gravitational interactions attribute non-metricity scalar $Q$. present work, consider two models which contains linear and non-linear form of scalar, specifically, $f(Q)=\alpha Q + \frac{\beta}{Q}$ \beta Q^2$, $\alpha$ $\beta$ are free then $(r,s)$ evaluated. We plot trajectory our $r-s$ plane. addition, physical behavior different cosmological such as density, deceleration, EoS parameters. Further, use Om both found predicts universe accelerating due component evolving non-metricity. Moreover, model I represents phantom type while II follows quintessence scenario.

Nonlocal teleparallel cosmology

Even though it is not possible to differentiate general relativity from teleparallel gravity using classical experiments, it could be possible to discriminate between them by quantum gravitational effects. These effects have motivated the introduction of nonlocal deformations of general relativity, and similar effects are also expected to occur in teleparallel gravity. Here, we study nonlocal d...

The Symmetric Teleparallel Gravity

We study symmetric teleparallel (STP) gravity model, in which only spacetime nonmetricity is nonzero. First we obtain STP equivalent Einstein-Hilbert Lagrangian and give an approach for a generic solution in terms of only metric tensor. Then we obtain a spherically symmetric static solution to the Einstein’s equation in STP space-time and discuss the singularities. Finally, we study a model giv...

f(T) teleparallel gravity and cosmology.

Over recent decades, the role of torsion in gravity has been extensively investigated along the main direction of bringing gravity closer to its gauge formulation and incorporating spin in a geometric description. Here we review various torsional constructions, from teleparallel, to Einstein-Cartan, and metric-affine gauge theories, resulting in extending torsional gravity in the paradigm of f ...

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...

Lagrange formulation of the symmetric teleparallel gravity

We develop a symmetric teleparallel gravity model, in which only spacetime nonmetricity is nonzero, in terms of the quadratic nonmetric Lagrangian. Then we perform a detailed calculation of variation which can be used for any gravitation formulation. Thus, we seek Scwarzschild-type solutions because of its observational success and obtain solutions which accept Scwarzschild-type, Scwarzschild-d...
