Kantowski-Sachs Universe Models in $f(T)$ Theory of Gravity
Abstract
The theory is recently proposed to explain the present cosmic accelerating expansion of the universe. theory is an extension of Teleparallel theory of gravity, where is the torsion scalar. This paper contains the construction of models within the Kantowski-Sachs universe. For this purpose, we use conservation equation and equation of state parameter, which represents the different phases of the universe. We discuss possible cases for the matter dominated era, radiation dominated era, present dark energy phase and their combinations. Particularly, a constant solution has been obtained which may correspond to the cosmological constant. Further, we consider two well known models and derive the equation of state parameter and discuss the cosmic acceleration. Also, the Hubble parameter and average scale factor have been evaluated.
