DESCRIPTION:Speaker: Christian Brennecke\nhosted by Laszlo Erdös\nAbstract
 : In this talk I will present a new derivation of the time-dependent Gross
 -Pitaveskii equation from a system of interacting bosons in $\\mathbb{R}^3
 $. Our derivation is based on a simple Gronwall estimate for suitably reno
 rmalized excitation number operators and yields optimal convergence rates.
  I will conclude the talk with some related open questions on the quasi-fr
 ee approximation of the many-body dynamics. The talk is based on joint wor
 ks with W. Kroschinsky and B. Schlein.
