- Abstract: Nonlocality is a distinctive feature of quantum theory, which has been
extensively studied for decades. It is found that the uncertainty principle
determines the nonlocality of quantum mechanics. Here we show that various
degrees of nonlocalities in correlated system can be characterized by the
generalized uncertainty principle, by which the complementarity is attributed
to the mutual dependence of observables. Concrete examples for different kinds
of non-classical phenomena pertaining to different orders of dependence are
presented. We obtain the third order ``skewness nonlocality'', and find that
the Bell nonlocality turns out to be merely the second order ``variance
nonlocality'' and the forth order dependence contains the commutator squares,
which hence is related to the quantum contextuality. More applications of the
generalized uncertainty principle are expected.

Three notions are often assumed to be essentially equivalent, representing different facets of the same phenomenon.
We analyze them in general Friedmann-Lemaitre- Robertson-Walker space-times through the lens of geometric structures on the classical phase space.
The analysis shows that: (i) inflation does not play an essential role; classical behavior can emerge much more generally; (ii) the three notions are conceptually distinct; classicality can emerge in one sense but not in another.

It is concluded that, within the framework of Quantum Mechanics, there is absolutely no reason to believe in the existence of non-Local effects.
