Abstract
The warm inflation scenario is an alternative mechanism which can explain the isotropic and homogeneous Universe in which we are living. In this work I extend a previously introduced formalism, without the restriction of the slow-roll regime. Quantum to classical transition of the fluctuations is studied by means of the `transition function' here introduced. I found that the fluctuations of radiation energy density decrease with time and the thermal equilibrium at the end of inflation holds.Keywords
