Gauge Orbit Types for Theories with Classical Compact Gauge Group
Alexander Hertsch, Gerd Rudolph, Matthias Schmidt
We determine the orbit types of the action of the group of local gauge transformations on the space of connections in a principal bundle with structure group O(n), SO(n) or …
On the algebra of quantum observables for a certain gauge model
Gerd Rudolph, Matthias Schmidt
We prove that the algebra of observables of a certain gauge model is generated by unbounded elements in the sense of Woronowicz. The generators are constructed from the classical g…
A gauge model for quantum mechanics on a stratified space
J. Huebschmann, G. Rudolph, M. Schmidt
In the Hamiltonian approach on a single spatial plaquette, we construct a quantum (lattice) gauge theory which incorporates the classical singularities. The reduced phase space is…
A Lattice Gauge Model of Singular Marsden-Weinstein Reduction. Part I. Kinematics
E. Fischer, G. Rudolph, M. Schmidt
The simplest nontrivial toy model of a classical SU(3) lattice gauge theory is studied in the Hamiltonian approach. By means of singular symplectic reduction, the reduced phase spa…
On the Topology of the Reduced Classical Configuration Space of Lattice QCD
S. Charzyński, G. Rudolph, M. Schmidt
We study the topological structure of the quotient of by diagonal conjugation. This is the simplest nontrivial example for the classical reduced configuration s…
On the Stratified Classical Configuration Space of Lattice QCD
S. Charzyński, J. Kijowski, G. Rudolph +1
The stratified structure of the configuration space $\mb G^N = G \times ... \times G$ reduced with respect to the action of by inner automorphisms is investigated for $G = SU(3…
