Query: Quasilinear systems of first order PDEs with nonlocal Hamiltonian
  structures   In this paper we wonder whether a quasilinear system of PDEs of first order
admits Hamiltonian formulation with local and nonlocal operators. By using the
theory of differential coverings, we find differential-geometric conditions
necessary to write a given system with one of the three Hamiltonian operators
investigated.
