Meromorphic connections on the Riemann sphere and quiver varieties (Japanese)
[ Abstract ]
I will show that some moduli spaces of meromorphic connections on the Riemann sphere are isomorphic to Nakajima's quiver varieties as complex symplectic manifolds (joint work with Kazuki Hiroe). This was conjectured by Boalch and generalizes Crawley-Boevey's result for logarithmic connections. Also I will mention Weyl group symmetries of isomonodromic deformations of meromorphic connections.
