Abstract
This paper provides an overview of warm inflation, an alternative to the standard cold inflationary model. Unlike cold inflation, warm inflation includes radiation during the inflationary period, maintaining a thermal bath, and eliminating the need for a separate reheating phase. The study examines the dynamics of warm inflation, focusing on the equations of motion of the inflaton field, energy scales, and the derivation of the primordial power spectrum, where thermal fluctuations dominate over quantum ones. The scalar dissipation function G(Q) from the literature is presented, enhancing the accuracy of power spectrum calculations and facilitating comparisons with empirical data. Various inflation models are reviewed for their compatibility with warm inflation and observational constraints, aiming to align theoretical predictions with cosmological observations.
