摘要：

We present numerical evidence for the hypothesis that, in the planar limit, four-dimensional Euclidean Yang-Mills theory on a finite symmetrical four-torus breaks chiral symmetry spontaneously when the length of the sides l is larger than a critical value l(c) with a bilinear condensate whose value is independent of l. Therefore spontaneous symmetry breaking occurs at finite volume and infinite N-c reduction holds for the chiral condensate. (C) 2004 Elsevier B.V. All rights reserved.
