Without aiming at a comprehensive review we shall try to discuss the conceptual setting and some results of these models such as to permit a comparison with environmental decoherence as it is discussed in this book.

Provided certain initial conditions hold, “coarsegraining” with respect to the irrelevant degrees of freedom may lead to the emergence of classical behaviour in the relevant part, since (almost) a

This program gave rise to the notion of ., — an expression coined by Zurek (1982) —, which goes back to the very early papers on the subject of decoherence by Zeh (1970) and Kübler and Zeh (1973, in particular Sect. 4). In our book this concept was already introduced

Algirdas Avižienis,Jean-Claude Laprieerse. The notion of an isolated system makes sense only as an approximation depending on the concrete situation. This point of view has been emphasized in the preceding chapters as the basis of the whole book. This chapter presents a self-contained discussion of the exact dynamics of a subsystem and
