Isomonodromic deformations and maximally stable bundles
Abstract
We consider irreducible tracefree meromorphic rank 2 connections over compact Riemann surfaces. By deforming the curve, the position of the poles and the connection, we construct the universal isomonodromic deformation of such a connection. We prove that the underlying vector bundle is generically maximally stable along the deformation. For surfaces of genus greater than 1, we get a non-trivial result even for regular connections.
