It is shown that the Gibbs factor of a plaquette with Wilson action is driven to 1 for all values of the “temperature” (coupling constant). WebThe results conform Migdal's scheme about the connection between four-dimensional gauge field and two-dimensional chiral system. And the recursion relation can be generalized to D dimensions gauge theories with chiral models in D-2 dimensions. fromis 9 album
