The authors study the weak coupling behaviour of the one-link integrals using their Schwinger-Dyson equations. In the first part the Schwinger- Dyson equations for the general O(N) group integral are established. Special attention is paid to the perturbative corrections to the large N limit. The second part is devoted to U(N) and SU(N) one-link group integrals and in this case the \(1/N^ 2\) correction is obtained explicitly.
