Fig. 1: Toy example of a bipartite system and its node ranking.
From: Ranking nodes in bipartite systems with a non-linear iterative map
The network is represented as a non directed, unweighted, bipartite network, a where a set of squared nodes, e.g., countries or pollinator animals, interact with a disjoint set of circular nodes, e.g., products or plants. Such a network is associated with the incidence matrix b in which the element is equal to 1 if there is a link between the two nodes. The panels from c−f show the scores and the rankings that Eq. (1) provides for four values of γ and are discussed in the main text. The black arrows between nodes are changes in the ranking with respect to the degree ranking.
