Analytic properties of npoint loops in perturbation theory

It is shown that simple perturbation graphs consisting of closedn- vertex loops have only the singularities possessed by reduced loops, obtained by ≪ fusing ≫ two or more of the vertices and omitting the internal lines which join them. The theorem holds providingn ⩾ 6.

Si dimostra che i grafici di perturbazione semplioi formati da anse chiuse conn vertici hanno solo le singolarità proprie delle anse ridotte ottemite ≪ fondendo ≫ due o più vertici e omettendo le linee interne che li uniscono. II teorema è valido purohèn⩾ 6.
