“…However, different universality classes appear for the (unoriented) critical configuration model when the law of the degree sequence has a finite second moment but an infinite third moment and heavy tails. For example, if the degree distribution is such that the probability that a vertex has degree k is asymptotic to c • k −γ for some constant c > and some γ ∈ (3, 4), then the sizes of connected components are of order n (γ−2)/(γ−1) , see for example [6,12,17].…”
