Query: The moduli space of stable vector bundles over a real algebraic curve   We study the spaces of stable real and quaternionic vector bundles on a real
algebraic curve. The basic relationship is established with unitary
representations of an extension Z/2 by the fundamental group. By comparison
with the space of real or quaternionic connections, some of the basic
topological invariants of these spaces are calculated.
