General Parallel Cosmology

Understand

General (tele)parallel Relativity, G$_\parallel$R, is the relativistic completion of Einstein's theories of gravity.

• The focus of this article is the derivation of the homogeneous and isotropic solution in G$_\parallel$R.
• The first-principles derivation, based on a non-trivial realisation of the symmetry, supersedes and unifies previous constructions of Riemannian and teleparallel cosmologies, and establishes the uniqueness of the physical solution.
• The constitutive law and the form of the material and inertial source currents is presented in the tensor (Palatini) formalism and adapted to the cosmological background, which exhibits novel features absent in the previously studied, static solutions to the theory.
