Spatially homogeneous and anisotropic Bianchi type-II, -VIII and -IX cosmological models filled with perfect fluid in the framework of the
f
(
R
,
T
) gravity proposed by Harko
et al.
(Phys. Rev. D
84
, 024020 (2011)) and also in general relativity have been studied. All the models obtained and presented here are anisotropic, expanding, non-rotating and also accelerating. Some important features of the models thus obtained have been discussed. We also noticed that the involvement of the new function
f
(
R
,
T
) does not affect the geometry of the space-time but slightly changes the matter distribution. |
