In a recent paper (Castagnino and Lombardi 2004), we have presented an explanation of decoherence different from the mainstream approach.  We have called ?self-induced decoherence? this new approach because, according to it, decoherence does not require the openness of the quantum system and its interaction with the environment: a single closed system can decohere when its Hamiltonian has continuous spectrum. The aim of the present talk is to explain two possible applications of this approach to decoherence.  The first one is the traditional problem of the classical limit of quantum mechanics.  The second application is the problem of quantum chaos.
