摘要：
A spatially homogenous and anisotropic Kantowski-Sachs space-time is considered in the presence of bulk viscous fluid containing one-dimensional cosmic strings in the framework of the f (R, T) gravity proposed by Harko et al. (Phys. Rev. D 84, 024020, (2011)). Some physically plausible conditions have been used to obtain a determinate solution of the field equations. A cosmological model, in this theory, is presented and some physical and kinematical properties of the model are also studied. © 2014, Società Italiana di Fisica and Springer-Verlag Berlin Heidelberg.
