| Outline of Final Research Achievements |
I constructed the framed moduli spaces of meromorphic connections on the projective line as complex symplectic manifolds, and furthermore with Boalch, constructed the quasi-Hamiltonian spaces parametering local generalized monodoromy data of meromorphic connections with a link. Also, with Hiroe, I showed that the moduli spaces of meromorphic connections with an unramified irregular singularity and arbitrary number of regular singularities are isomorphic to Nakajima quiver varieties. Furthermore I checked that the isomonodromy tau functions induce the Hamiltonians for isomonodromic deformations in some sense, and showed that the Fourier-Laplace transform of meromorphic connections induce symmetry of isomonodromic deformation equations.
