Hamiltonian structures of isomonodromic deformations on moduli spaces of   parabolic connections
  In this paper, we treat moduli spaces of parabolic connections. We take \'etale coverings of the moduli spaces, and we construct a Hamiltonian structure of an algebraic vector field determined by the isomonodromic deformation for each \'etale morphism.
