摘要
In this work, we have studied LRS Bianchi type I cosmological models in f(R,T) gravity with tilted observers, where R is the Ricci scalar and T is the trace of the stress energy tensor. We have explored a tilted model and determined the solutions of the field equations by assuming special law of variation of Hubble's parameter, proposed by Berman (1983) that yields constant deceleration parameter. In this scenario, we have used the equation of state p = (gamma - 1)rho and power law of velocity to describe the different anisotropic physical models such as Dust Universe, Radiation Universe, Hard Universe and Zedovich Universe. We have discussed graphical presentation of all parameters of the derived models with the help of MATLAB. Some physical and geometrical aspects of the models are also discussed.
