Kantowski–Sachs Cosmological Model with Anisotropic Dark Energy in Lyra Geometry

Abstract

This paper deals with the study of Kantowski–Sachs universe in the presence of an anisotropic dark energy within the framework of Lyra geometry. A special form of time-varying deceleration parameter and present non-singular cosmological model were used to obtain exact solutions of Einstein's field equations. The physical and geometric features of the cosmological model were discussed. Under suitable condition, it was observed that the anisotropy parameter of the universe and the skewness parameter of the dark energy approach to zero for large cosmic time. The results were found to be consistent with the recent observations on the present-day universe. © 2018, The National Academy of Sciences, India.
