Abstract
A new model of warm inflation without slow-roll conditions for the sca lar field is studied. Classicality conditions that must be satisfied t o have an effective stochastic approach in the warm inflation scenario are analyzed for a general coarse-grained field, defined with a funct ion that describes the long wavelength suppression. The theory can pre dict the spectral density of the fluctuations of the field which can b e compared with the COBE data. [S0556-2821(98)11020-2].
