DESCRIPTION:Title: Derivation of Wave Kinetic Equations in 1D.\n\nAbstract:
  \n\nWave kinetic equations describe the effective behavior of dispersive 
 systems in an appropriate large box limit\, called the kinetic limit. Such
  equations have been derived in dimension at least 2 up to or beyond the k
 inetic timescale. In this talk\, we address the question of deriving wave 
 kinetic equations in dimension one. Just as with higher dimensional system
 s\, we may approach the derivation by expanding the solution into iterates
 \, represented by Feynman diagrams. However\, bounding these diagrams in d
 imension one proves significantly more difficult than in higher dimensions
 . Here\, we focus on the derivation of the kinetic equation for the 1D MMT
  (Majda\, McLaughlin\, and Tabak) system\, deriving it for subcritical tim
 escales\, and address similar progress for other one-dimensional systems.
