Scale-free networks exhibit power-law distributions. The scaling exponent can be analyti- cally estimated by calculating the probability density function. Now, assume that a network exhibits power-law degree distribution in the form of P ( f) = Cf ? ? where P ( f) measures the probability of how many nodes have degree f , C is the normalized constant, and ? is the scaling exponent. Also note that all network nodes have positive real values of degree with the minimum degree of fmin. Prove that the degree distribution of the network can be represented as
