Bianchi Type-II Oscillating String Cosmological Model in f(R, T) Gravity

Abstract

A spatially homogeneous and anisotropic Bianchi type-II cosmological model is obtained in f(R, T) theory of gravity (Harko et al., Phys. Rev. D 84, 024020, 2011) when the source for energy momentum tensor is one-dimensional cosmic strings. We obtained a string cosmological model using a time periodic varying deceleration parameter proposed by Shen and Jiang (2014). Some physical and kinematical properties of the model are also discussed.
