DEGREE SEQUENCES BEYOND POWER LAWS IN COMPLEX NETWORKS

  • Fund Project:
  • Many complex networks possess vertex-degree distributions in a power-law form of ck-γ, where k is the degree variable and c and γ are constants. To better understand the mechanism of power-law formation in realworld networks, it is effective to analyze their degree variable sequences. We had shown before that, for a scale-free network of size N,if its vertex-degree sequence is k1 < k2 <…< kl, where {k1, k2,…, kl} is the set of all unequal vertex degrees in the network, and if its power exponent satisfies γ>1, then the length l of the vertex-degree sequence is of order logN. In the present paper, we further study complex networks with more general distributions and prove that the same conclusion holds even for non-network type of complex systems. In addition, we support the conclusion by verifying many real-world network and system examples. We finally discuss some potential applications of the new finding in various fields of science, technology and society.
