| dc.description.abstract | The purpose of this effort is to find out role of tilted and non-tilted congruence in the dynamics dissipative Lemaitre-Tolman-Bondi space-time in f(G, T) gravity, where T is stress energy momentum tensor and G represents Gauss-Bonnet invariant. We use kinematical and dynamical variables to discuss the inhomogeneity factor and its evolution. It has been discovered that emergence of the inhomogeneity factor depends upon heat flux, shear tensor, and expansion scalar for tilted observer, whereas for non-tilted observers, it depends upon the shear tensor. Additionally, we investigate non-tilted congruence stability requirements in the presence of a dark source terms and deduce that instability of the non-tilted congruence is caused by expansion. We also observed that Einstein tensor is same for both tilted and non-tilted congruence and energy density is standard for both tilted and non-tilted observer. | |
