LRS Bianchi-I transit universe with periodic varying q in f (R, T) gravity

( )We have investigated the cosmic transit behavior of LRS Bianchi-I universe in modified f (R, T) gravity theory whose functional form is taken as f (R,T) = R + 2f (t), where R is Ricci scalar and T is the energy-momentum tensor. Subjecting the deceleration parameter q to periodic variations as q - k cos(beta t) - 1, where k, beta > 0, the oscillatory behavior of EoS parameter and violation of energy-momentum conservation in the wide range of parameters have been observed. Hubble parameter oscillates but remains positive which signify the alternate decelerating and accelerating expansion of universe with no singularity.
