Shear-free anisotropic cosmological models in f (R) gravity
(Springer, 2016)We study a class of shear-free, homogeneous but anisotropic cosmological models with imperfect matter sources in the context of f(R) gravity. We show that the anisotropic stresses are related to the electric part of the ...
