In science:

Topical search algorithms in reference (d) in reveal a similar structure with the authority-and-hub nodes. Recently several other search algorithms that utilize local information in a power-law graph with symmetric links were proposed, see reference (c) in .

Notice again that this structural discovery resembles the mutually reinforcing relationship of Kleinberg’s authorities and hubs.
A Connection-Centric Survey of Recommender Systems Research
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.
Random Networks with Tunable Degree Distribution and Clustering
Although the areas of space visited can be regarded as the hubs of the present problem, the main difference is the displacement of the walk.
