Higher dimensional perfect fluid cosmological models in f(R,T) gravity

Abstract

A new class of spatially homogeneous Kaluza–Klein cosmological models filled with perfect fluid in the framework of f(R,T) gravity proposed by Harko et al. (2011) have been studied with a general choice of the function f(R,T). The models obtained and presented here are anisotropic, expanding and free from singularities for  n>0 and it is established that the additional condition, special law of variation of Hubble parameter proposed by Bermann (1983), taken by Reddy et al. (2012b) is superfluous.  Also some important features of the models, thus obtained, have been discussed.
