Moduli spaces of meromorphic connections, quiver varieties, and integrable deformations (1506.03230v2)
Published 10 Jun 2015 in math.CA, math.AG, and math.RT
Abstract: This is a note in which we first review symmetries of moduli spaces of stable meromorphic connections on trivial vector bundles over the Riemann sphere, and next discuss symmetries of their integrable deformations as an application. In the study of the symmetries, a realization of the moduli spaces as quiver varieties is given and plays an essential role.
