The hub is the node with the maximal number of outgoing edges, T.
Subgraphs in random networks
At γ ≤ 2, there is a condensation effect , where a finite fraction of the nodes have outdegree ≤ 1, and the mean hub size becomes proportional to N.
Subgraphs in random networks
For γ ≤ 2 the network is in a condensed regime, where the hub T = O(N ).
Subgraphs in random networks
In this regime, the hubs no longer contribute significantly to the subgraph distribution.
Subgraphs in random networks
We let θ0 = p1 − Pi θ2 i . A vertex i ≥ 1 with θi > 0 then corresponds to a “hub” or “attracting center” for the mapping, because significantly many more integers are likely to be mapped to it as n gets large than to those for which θi = 0.

This has the effect of limiting the ability to act as hubs for low-degree vertices, and consequently the network disconnects into smaller components.
