Abstract. We consider a system constituted by $N$ identical particles
interacting by means of a meanfield Hamiltonian. The evolution of the
above system is taken into account both in the classical and in the
quantum framework, as well as the corresponding effective dynamics
when $N o\infty$. It is well known that, in the limit $N o\infty$,
the oneparticle state obeys to the Vlasov equation, in the classical
case, and to the Hartree equation, in the quantum framework. Moreover,
in both situations propagation of chaos holds. In this work, we
present an overview over known results concerning the problem, with
particular attention to the case of smooth pairinteraction
potentials, and we analize the link between the asymptotics
$N o\infty$ (MeanField Limit) and the semiclassical aprroximation
($\hbar o 0$). We dicuss and present in a unified way some known
results, highlighting some open problems on that topic. In particular,
we discuss in a wider way the result presented in [29] (see
References), giving even an outlook on generalizations and possible
applications.
