摘要：
In this paper, we have investigated the perfect fluid matter distribution with different quadratic equation of states (EoS) parameters in the form (i) p = p(0) + alpha rho + beta rho(2), (ii) p= alpha rho + rho(2)/rho(c) and (iii) p = alpha rho(2) - rho for Marder space-time in f(R,T) theory. The field equations of f(R,T) gravity with the inclusion of cosmological parameter Lambda have been derived for the first case of Harko et al. (Phys Rev D 84(2):024020, 2011) in the form f(R,T)=R + 2f(T). The physical parameters are investigated and its properties are studied.
