Query: Moment classification of infinite energy solutions to the homogeneous
  Boltzmann equation   In this paper, we will introduce a precise classification of characteristic
functions in the Fourier space according to the moment constraint in the
physical space of any order. Based on this, we construct measure valued
solutions to the homogeneous Boltzmann equation with the exact moment condition
as the initial data.
