## Abstract Let __G__ be a compact Hausdorff group. A subspace __X__ of __G topologically generates G__ if __G__ is the smallest closed subgroup of __G__ containing __X__. Define __tgw__ (__G__) = __ω__ · min{__w__ (__X__): __X__ is closed in __G__ and topologically generates __G__ }, where __w__
In a world with exact SUN symmetry Veneziano has proposed a topological expansion in terms of the small dimensionless parameter I )I N2. We relate this convergence factor to the density of hadronic states. The weakness of higher-order corrections (i.e., 1 /N2) is interpreted as reflecting the small
