Abstract :
In this paper, LRS Bianchi-I space-time is considered in the presence of perfect fluid source in the frame work of teleparallel gravity which is so called f(Q) gravity, where f(Q) is the function of non-metricity scalar Q. This non-metricity scalar Q is responsible for the gravitational interaction. We have considered a special form of the f(Q) function which is given as f(Q) = ?Qn, (where ? and n both are the dynamical model parameters). The Einstein’s field equations have been solved by taking into account the special form of deceleration parameter. The geometrical and physical aspect of the model is also studied. We find that the model has initial singularity and the physical parameters diverge at the initial epoch. The model resemble ?CDM model for large time t.
