The global well posedness of the Boltzmann hierarchy near vacuum

Abstract/Media

Zoom Link

I will discuss the global existence and uniqueness theory for a statistical generalization of the Boltzmann equation called the Boltzmann hierarchy. This hierarchy arises when considering non-chaotic initial data for an infinite gas of interacting hard spheres, and in Lanford's derivation of the Boltzmann equation from the BBGKY hierarchy. A novel part of the uniqueness proof employs a combinatorial technique known as the Klainerman-Machedon board game argument, employed originally in the context of dispersive equations. This is joint work with Ampazoglou, Pavlovic, and Taskovic.
