Analytic derivation of dual gluons and monopoles from SU(2) lattice   Yang-Mills theory. III. Plaquette representation
  In this series of three papers, we generalize the derivation of dual photons and monopoles by Polyakov, and Banks, Myerson and Kogut, to obtain approximative models of SU(2) lattice gauge theory. Our approach is based on stationary phase approximations.   In this third article, we start from the plaquette representation of 3-dimensional SU(2) lattice gauge theory. By extending a work of Borisenko, Voloshin and Faber, we transform the expectation value of a Wilson loop into a path integral over a dual gluon field and monopole variables. The action contains the tree-level Coulomb interaction and a nonlinear coupling between dual gluons, monopoles and current.   We show that this model exhibits confinement if a condition on the monopole self-energy is satisfied.
