چکیده

Abstract The Noether symmetry analysis is applied in a multiscalar field cosmological model teleparallel gravity. In particular, we consider two scalar fields with interaction scalar-torsion theory. equations have minisuperspace description, and the evolution of physical variables depends on potential function that drives fields’ dynamics. With requirement for to admit non-trivial point symmetries use first theorem Noether, constrain all functional forms potential. Finally, apply vectors corresponding conservation laws determine exact analytic solutions multiscalar-torsion cosmology.

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...

Tensor-multiscalar theories from multidimensional cosmology.

Inhomogeneous multidimensional cosmological models with a higher dimensional spacetime manifold M = M0 × ∏n i=1 Mi (n ≥ 1) are investigated under dimensional reduction to tensor-multi-scalar theories. In the Einstein conformal frame, these theories take the shape of a flat σ-model. For the singular case where M0 is 2-dimensional, the dimensional reduction to dilaton gravity is preformed with di...

Exact Solutions, Symmetries and Quantization of Two-dimensional Higher-derivative Gravity with Dynamical Torsion

We investigate two-dimensional higher derivative gravitational theories in a Riemann-Cartan framework. We obtain the most general static black hole solutions in conformal coordinates and discuss their geometry. We also consider the hamiltonian formulation of the theory and discuss its symmetries, showing that it can be considered as a gauge theory of a non-linear generalizations of the 2-dimens...
