Description

Various properties of the group weight of Feynman graphs in non-Abelian gauge theories are discussed. Infinitely many skeleton graphs with vanishing weight are exhibited for every compact Lie group. The 1/N2 dependence of the topological expansion is related to a 1/N2 expansion in some channels with the exchange of definite quantum numbers
