Prequantization of the moduli space of flat connections over a four-manifold

چکیده
We introduce a symplectic structure on the space of connections in a G-principal bundle over a four-manifold and the Hamiltonian action on it of the group of gauge transformations which are trivial on the boundary. The symplectic reduction becomes the moduli space of flat connections over the manifold. On the moduli space of flat connections we shall construct a hermitian line bundle with connection whose curvature is given by the symplectic form. This is the ChernSimons prequantum line bundle. The group of gauge transformations on the boundary of the base manifold acts on the moduli space of flat connections by an infinitesimally symplectic way. This action is lifted to the prequantum line bundle by its abelian extension. MSC: 57R; 58E; 81E. Subj. Class: Global analysis, Quantum field theory.

Chern-Simons pre-quantization over four-manifolds
We introduce a pre-symplectic structure on the space of connections in aG-principal bundle over a four-manifold and a Hamiltonian action on it of the group of gauge transformations that are trivial on the boundary. The moment map is given by the square of curvature so that the 0-level set is the space of flat connections. Thus the moduli space of flat connections is endowed with a pre-symplecti...
متن کاملOn Casson-type Instanton Moduli Spaces over Negative Definite Four-manifolds
Recently Andrei Teleman considered instanton moduli spaces over negative definite four-manifolds X with b2(X) ≥ 1. If b2(X) is divisible by four and b1(X) = 1 a gauge-theoretic invariant can be defined; it is a count of flat connections modulo the gauge group. Our first result shows that if such a moduli space is non-empty and the manifold admits a connected sum decomposition X ∼= X1#X2 then bo...
متن کاملModuli spaces of self-dual connections over asymptotically locally flat gravitational instantons
We investigate Yang–Mills instanton theory over four dimensional asymptotically locally flat (ALF) geometries, including gravitational instantons of this type, by exploiting the existence of a natural smooth compactification of these spaces introduced by Hausel– Hunsicker–Mazzeo. First referring to the codimension 2 singularity removal theorem of Sibner–Sibner and R̊ade we prove that given a smo...
متن کاملThe Volume of the Moduli Space of Flat Connections on a Nonorientable 2-manifold
We compute the Riemannian volume of the moduli space of flat connections on a nonorientable 2-manifold, for a natural class of metrics. We also show that Witten’s volume formula for these moduli spaces may be derived using Haar measure, and we give a new proof of Witten’s volume formula for the moduli space of flat connections on a Riemann surface using Haar measure. ———————–

Recently Andrei Teleman considered instanton moduli spaces over negative definite four-manifolds X with b2(X) ≥ 1.
