In teleparallel geometries, the coframe and corresponding spin connection are the principal geometric objects and, consequently, the appropriate definition of a symmetry is that of an affine symmetry. The set of invariant coframes and their correspon...
This paper investigates the teleparallel Robertson–Walker (TRW) F(T) gravity solutions for a Chaplygin gas, and then for any polytropic gas cosmological source. We use the TRW F(T) gravity field equations (FEs) for each k-parameter value case a...
This paper investigates the teleparallel Robertson–Walker (TRW) F(T) gravity solutions for a scalar field source. We use the TRW F(T) gravity field equations (FEs) for each k-parameter value case added by a scalar field to find new teleparallel...
We investigate the teleparallel Robertson–Walker (TRW) F(T)-gravity solutions for a cosmological electromagnetic source in the current paper. We use and solve the TRW F(T)-gravity field equations (FEs) for each value of the k-parameter (−...
In this paper, we find several teleparallel F(T,B) solutions for a Robertson–Walker (TRW) cosmological spacetime. We first set and solve the F(T,B)-type field equations for a linear perfect fluid. Using similar techniques, we then find new F(T,...
Self-similar cosmological solutions correspond to spacetimes that admit a homothetic symmetry. The physical properties of self-similar solutions can describe important eras of the cosmological evolution. Recently, self-similar cosmological solutions...
In a spatially flat Friedmann–Lemaître–Robertson–Walker background space, we consider a scalar-torsion gravitational model which has similar properties to the dilaton theory. This teleparallel model is invariant under a discrete transformation simila...
