Large-NReduction in the Continuum Three-Dimensional Yang-Mills Theory

Numerical and theoretical evidence leads us to propose the following: Three-dimensional Euclidean Yang-Mills theory in the planar limit undergoes a phase transition on a torus of side $l=l_c$. For $l>l_c$ the planar limit is $l$ independent, as expected of a noninteracting string theory. We expect the situation in four dimensions to be similar.
