Study of axially symmetric anisotropic massive string cosmological model in f(r, t) theory of gravity

Axially symmetric anisotropic cosmological model with massive string fluid source are obtained in  f(R,T)  theory of Gravity proposed by Harko et al.(Phys.Rev.D 84,02420,2011).The model which we obtained study geometric (Nambu) string and Reddy string in f(R,T) theory of gravity. Some physical properties of the model are also discussed.
