Outline of Final Research Achievements

I gave an isomorphism between a moduli space of algebraic differential equations on the Riemann sphere and quiver variety as symplectic manifolds when differential equations have at most one unramified irregular singular point. When the differential equations have arbitrary number of unramified irregular singular points, although it was known that the moduli space can not be isomorphic to any quiver varieties, I constructed an open embedding into a quiver variety which is not surjective in general and clarified a relation between middle convolution of differential equations and Wely group of the quiver, also determined a necessary and sufficient conditon to the nonemptiness of the regular part of the moduli space.
