| Abstract: | 4 dimensional Yukawa-type theories with an internal SU(N) symmetry group are studied in the large N limit by means of path integral techniques. For a simplified model where the bosonic field transforms as a singket under SU(N), we explicitly solve the gap equation and shiw that the symmetry is spontaneously broken. |
