    "abstract": "A generalized formal framework for decoherence, that can be used both in open\nand closed quantum systems, is sketched. In this context, the relationship\nbetween the decoherence of a closed system and the decoherence of its\nsubsystems is studied, and the corresponding decoherence times are defined: for\nmacroscopic systems, the decoherence time of the closed system is much greater\nthan the decoherence time of its subsystems. Finally, it is shown that the\napplication of the new formal framework to a well-known model leads to\nphysically adequate results.",
