Query: Global classical solutions of the Vlasov-Darwin system for small initial
  data   A global-in-time existence theorem for classical solutions of the
Vlasow-Darwin system is given under the assumption of smallness of the initial
data. Furthermore it is shown that in case of spherical symmetry the system
degenerates to the relativistic Vlasov-Poisson system.
