Cosmological Issues in F(T) Gravity Theory
Abstract
We review recent developments on cosmology in extended teleparallel gravity, called "F(T) gravity" with T the torsion scalar in teleparallelism. We explore various cosmological aspects of F(T) gravity including the evolution of the equation of state for the universe, finite-time future singularities, thermodynamics, and four-dimensional effective F(T) gravity theories coming from the higher-dimensional Kaluza-Klein (KK) and Randall-Sundrum (RS) theories.
