    Effects of Well-Known Potentials on Cosmic Inflation in f(T) Gravity
    (Library Information Services, CUI Lahore, 2023) Ayesha Aslam; FA21-RMT-064; Dr. Abdul Jawad
    In this thesis, we investigate a canonical scalar ¯eld in°ationary scenarioby considering an exponential model in the context of f (T ) theory. We take some well-known potentials as general hilltop in°ation potential (GHI), valley hybrid in°ation potential (VHI), shaft potential and minimal in°ation potential to evaluate some in°ationary parameters. We evaluate number of e-folds N , the slow-roll parameter ²1, ratio of tensor-scalar r, scalar-spectral index (ns) and its running ®. For a comparison of our results with Planck data, we draw ns - r and ns - ®s planes for the di®erent well known potentials. Our outcomes for three potentials depict a consist and compatible in°ationary scenario with the recent observational data (Planck data 2018).
