Query: Euler-type equations and commutators in singular and hyperbolic limits
  of kinetic Cucker-Smale models   This paper deals with the derivation and analysis of a compressible
Euler-type equation with singular commutator, which is derived from a
hyperbolic limit of the kinetic description to the Cucker-Smale model of
interacting individuals
