dc.description.abstractThe current paper reports an investigation of a warm inflationary scenario in the context of f (T ) gravity for a spatially flat FLRW universe. In our model, inflation is driven purely by the torsional sector of f (T ) gravity, without introducing any additional scalar fields.We focus on the high dissipative regime (R >> 1), reconstruct the Hubble parameter as a function of the e-folding number N, and derive the slow-roll parameters ε1(N) and ε2(N). The study has encapsulated the dynamics of inflation and its duration under strong dissipation. The dissipative coefficient Γ is modeled with a temperature-dependent power-law form, linking the inflationary dynamics to thermal corrections and the particle content of the early universe. The analysis has affirmed that the torsion-induced energy density ρT successfully transitions to radiation energy density ρrad, facilitating a graceful exit from inflation. Finally, we have validated our model by comparing the scalar spectral index and tensor-to-scalar ratio with Planck 2018 results, demonstrating consistency within observational bounds. Additionally, it is verified that the thermal domination condition T∗/H > 1 and the torsion dominance condition ρT /ρrad > 1 are satisfied.
