Description
Consider a system of $N$ bosons interacting via a repulsive short
range pair potential. Let $\psi_{N,t}$ be the solution to the Schrödinger
equation of the N-particle dynamics. We prove that the one-particle density
matrix of $\psi_{N,t}$
solves the time-dependent Gross-Pitaevskii equation, a cubic non-linear
Schrödinger equation.
We shall also review general problems related to quantum dynamics of N
particle systems.
