Scalar field source Teleparallel Robertson-Walker F(T)-gravity solutions
Abstract
This paper investigates the teleparallel Robertson--Walker (TRW) gravity solutions for a scalar field source. We use the TRW gravity field equations (FEs) for each -parameter value case added by a scalar field to find new teleparallel solutions. For , we find an easy-to-compute solution formula applicable for any scalar field source. Then, we obtain, for and situations, some new analytical solutions, only for specific -parameter values and well-determined scalar field cases. We can find by those computations a large number of analytical teleparallel solutions independent of any scalar potential expression. The independence makes the FE solving and computations easier. The new solutions will be relevant for future cosmological applications in dark matter, dark energy (DE) quintessence, phantom energy and quintom models of physical processes.
