    (Library Information Services, CUI Lahore, 2023) Muhammad Hamza Rasool; CIIT/FA21-RMT-047/LHR; DR. RABIA SALEEM
    In this thesis, our aim is to study cosmic warm inflation (WI) in the frameworkof f (Q) gravity, where Q represents the non-metricity scalar. In this context, we introduce the Tsallis, Renyi, and Barrow holographic dark energy (BHDE) entropies into the standard Friedmann equations. Under the slow-roll (SR) ap- proximation, we find exact solutions for the inflaton field, the effective potential necessary to produce inflation, and the scale factor while considering both low and high-dissipative regimes. We calculate some important parameters, includ- ing SR parameters, the number of e-folds (N ), the scalar spectral index (nS) and
