Scale-free property for degrees and weights in an N-interactions random graph model

Probability 2013-09-18 v1

Abstract

A general random graph evolution mechanism is defined. The evolution is a combination of the preferential attachment model and the interaction of N vertices (N>=3). A vertex in the graph is characterized by its degree and its weight. The weight of a given vertex is the number of the interactions of the vertex. The asymptotic behaviour of the graph is studied. Scale-free properties both for the degrees and the weights are proved. It turns out that any exponent in (2,\infty) can be achieved. The proofs are based on discrete time martingale theory.
