Query: Future attractors of Bianchi types II and V cosmologies with massless
  Vlasov matter   It is shown that the generalized Collins--Stewart radiation and Milne
solutions are attractors of the massless Einstein--Vlasov system for Bianchi
types II and V spacetimes, respectively. The proof is based on an energy method
and bootstrap argument which are used to determine the decay rates of the
perturbations away from the attractors.
