摘要：
In this paper, we have studied the Einstein-Rosen space time in f (R, T) gravity by considering the second model of Harko et al. (Phys. Rev. D 84: 024020, 2011), f (R, T) = f(1)(R)+ f(2)(T), where f(1)(R) = lambda R; f(2)(T) = lambda T and f(1)(R) = lambda R; f(2)(T) = lambda T-2. The matter field is considered in the form of perfect fluid. It is observed that, the perfect fluid represent the Zel'dovich universe in both the forms.
