Title: Reduction of dynamical degrees of freedom in the large-N gauge theory

Journal Article · · Phys. Rev. Lett.; (United States)

It is pointed out that the factorization of disconnected Wilson loop amplitudes implies a major reduction in the dynamical degrees of freedom in the large-N limit of lattice gauge theory; the original model may be replaced by a much simpler one (d is the space-time dimensionality), Z = Pi/sub ..mu../..integral..dU/sub ..mu../ exp(..beta sigma../sup d/= 1 trU/sub ..mu../U/sub ..nu../U/sup dagger//sub ..mu../U/sup dagger//sub ..nu../). Thus the field theory may be reduced to an integration over a finite number of matrices in the large-N limit.
