Abstract:
Improving on an earlier proposal, we construct the gauge theories of the quantum groups Uq(N)U_q(N). We find that these theories are consistent also with an ordinary (commuting) spacetime. The bicovariance conditions of the quantum differential calculus are essential in our construction. The gauge potentials and the field strengths are qq-commuting ``fields", and satisfy qq-commutation relations with the gauge parameters. The transformation rules of the potentials are given explicitly, and generalize the ordinary infinitesimal gauge variations. The qq-lagrangian invariant under the Uq(N)U_q(N) variations has the Yang-Mills form \Fmn~i \Fmn~j g_{ij}, the ``quantum metric'' gijg_{ij} being a generalization of the Killing metric.
