In this talk, we look at the derivation of a certain type of NLS from many-body interactions of bosonic particles with many-body interactions. We establish convergence of the BBGKY to the (Gross-Pitaevskii) GP hierarchy by adapting the arguments originated from the work of Erd?s-Schlein-Yau. While for the proof of uniqueness on factorized solutions to the infinite GP hierarchy, we expand the so called "board game" approach introduced by Klainerman-Machedon.
