Stratified cohesiveness in complex business networks

This paper presents a new definition of the community structure network, which takes also into account how communities are stratified. In particular, we extend standard concept clustering coefficient and provide local $l$-adjacency node $i$. We define it as an opportunely weighted mean coefficients nodes at distance $l$ from The stratus associated to $i$ is identified by $i$, so that peculiar $l=0$. As varies, then used infer insights on entire network. Empirical experiments special business networks carried out. analysis air traffic validate theoretical proposal supporting arguments its usefulness.
