ABSTRACT
I will discuss a theorem that characterizes the behavior of solutions of focussing nonlinear Schr\"odinger equation with a potential, for initial data that looks like a point particle. The theorem proves that, in the semiclassical limit, this particle persists and evolves via the classical Newtonian trajectory. This resolves a conjecture of A. Weinstein that dates from about 1980.
