Abstract

We show that in preferential attachment models with power-law exponent τ∈(2,3) the distance between randomly chosen vertices in the giant component is asymptotically equal to (4+o(1)) (loglog N)/(-log (τ-2)), where N denotes the number of nodes. This is twice the value obtained for several types of configuration models with the same power-law exponent. The extra factor reveals the different structure of typical shortest paths in preferential attachment graphs.
