A. Ashtekar et J. Lewandowski, COMPLETENESS OF WILSON LOOP FUNCTIONALS ON THE MODULI SPACE OF SL(2, C) AND SU(1, 1) CONNECTIONS, Classical and quantum gravity, 10(6), 1993, pp. 69-74
The structure of the moduli spaces M := A/G of (all, not just flat) SL
(2, C) and SU(1, 1) connections on an n-manifold is analysed. For any
topology on the corresponding spaces A of all connections which satisf
ies the weak requirement of compatibility with the affine structure of
A, the moduli space M is shown to be non-Hausdorff. It is then shown
that the Wilson loop functionals-4.e. the traces of holonomies of conn
ections around closed loops-are complete in the sense that they suffic
e to separate all separable points of M. The methods are general enoug
h to allow the underlying n-manifold to be topologically non-trivial a
nd for connections to be defined on non-trivial bundles. The results h
ave implications for canonical quantum general relativity in four and
three dimensions.
