Query: Entanglement and Properties   Various topics concerning the entanglement of composite quantum systems are
considered with particular emphasis concerning the strict relations of such a
problem with the one of attributing objective properties to the constituents.
In particular we will focus our attention to composite quantum systems composed
of identical constituents, with the purpose of dealing with subtle issues,
which have never been adequately discussed in the literature, originating from
the true indistinguishability of the subsystems involved.
