Query: Quasi-Hamiltonian Geometry of Meromorphic Connections   For each connected complex reductive group G, we find a family of new
examples of complex quasi-Hamiltonian G-spaces with G-valued moment maps. These
spaces arise naturally as moduli spaces of (suitably framed) meromorphic
connections on principal G-bundles over a disc, and they generalise the
conjugacy class example of Alekseev, Malkin and Meinrenken (which appears in
the simple pole case). Using the `fusion product' in the theory this gives a
finite dimensional construction of the natural symplectic structures on the
spaces of monodromy/Stokes data of meromorphic connections over arbitrary genus
Riemann surfaces, together with a new proof of the symplectic nature of
isomonodromic deformations of such connections.
