    Cosmographic Analysis of Holographic Non-Zero Torsion Framework
    (Library Information Services, CUI Lahore, 2023) Aitazaz Ahsan; FA21-RMT-018; Dr. Abdul Jawad
    In this thesis, we use the cosmographic approach to discuss Friedmann-like space-time in the presence of torsion. For this, we explore equations of motion that explain creation in an isotropic and homogeneous cosmic backdrop with non-zero torsion. Here, we consider the energy density of p L¡2. We examine this DE model with both constant and variable holographic length-scale in terms of Hubble parameter to determine the best ¯t scale. The interaction between dark sector components is taken to evaluate cosmographic parameters, like Hubble, equation of state, deceleration, jerk, snap, lerk the state¯nder pa- rameters. We consider four c(z) parameterizations, which are Chevalier- Polarski-Linder, Jassal-Bagla-Padmanabhan, Wetterich and Ma-Zhang for both cases. We obtain consistent results for speci¯c choices of constant parameters in the underlying scenario.
