Given a space and a group , a -flat connection or -local system is a map , or equivalently a map . A moduli space of flat connections is a moduli space/moduli stack of such structure.
The moduli space of flat connections for suitable Lie groups over Riemann surfaces appears as the phase space of -Chern-Simons theory over these surfaces. It carries itself a projectively flat connection, the Knizhnik-Zamolodchikov connection or Hitchin connection.
The Narasimhan–Seshadri theorem asserts that the moduli space of flat connections on a Riemann surface is naturally a complex manifold.
