Kantowski–Sachs Spherically Symmetric Solutions in Teleparallel F(T) Gravity
Alexandre Landry
Source abstract
In this paper, we investigate time-dependent Kantowski–Sachs spherically symmetric teleparallel F(T) gravity in vacuum and in a perfect isotropic fluid. We begin by finding the field equations and solve for new teleparallel F(T) solutions. With a power-law ansatz for the co-frame functions, we find new non-trivial teleparallel F(T) vacuum solutions. We then proceed to find new non-trivial teleparallel F(T) solutions in a perfect isotropic fluid with both linear and non-linear equations of state. We find a great number of new exact and approximated teleparallel F(T) solutions. These classes of new solutions are relevant for future cosmological applications.
