摘要
In this article, we explore the comprehensive narrative of cosmic evolution within a cosmological framework byutilizing a novel form of gravity known as generalized symmetric teleparallel gravity, denoted asf(Q,T) gravity. Here,Qrepresents the non-metricity scalar, whileTdenotes the trace of the energy-momentum tensor. We present and analyze twodistinctf(Q,T) cosmological models, each characterized by its unique Lagrangian. Our investigation delves into thecosmological parameters of these models, scrutinizing various energy conditions, examining the inflationary dynamics ofthe early universe through scalar field formulations, and probing the mysterious nature of dark energy using statefinderdiagnostics and(omega-omega')phase space analysis. Ultimately, our findings offer a comprehensive account of cosmic evo-lution, spanning from the early universe to its late-time evolution
