Anisotropic cosmological models in f(T) theory of gravity with mixture of fluids

Abstract

This study presents anisotropic cosmological models in f(T) theory of gravity with mixture of fluids. The \(f\left( T \right)\) theory of gravity is the generalization of the Teleparallel theory of gravity, where T is the torsion scalar. In order to obtain a deterministic solution of the field equations, I have assumed that the two sources of the perfect fluid and dark energy interact minimally with separate conservation of their energy–momentum tensors as well EoS parameter of the perfect fluid is assumed to be constant. In this paper, I have investigated dark energy models such as quintessence, chaplygin gas, cosmological constant with assist of f(T) gravity. Role of the cosmological constant \(\Lambda\) term in the evolution of the anisotropic universe has been studied. The diagnostics parameters \(r(z)\), \(s(z)\) and \(om(z)\) are investigated. I have discussed observational fitting concerning.
