Abstract
Bianchi type-IX space-time is considered in the framework of the ƒ(R) theory of gravity when the source of the energy momentum tensor is a perfect fluid. The cosmological model is obtained by using the condition that the expansion scalar (θ) is proportional to the shear scalar (σ). The physical and geometrical properties of the model are also discussed.
Keywords: ƒ(R) gravity, Bianchi type-IX space-time
