Many networks such as the Internet have been found to possess scale-free and small-world network properties reflected … by so-called power law distributions. Scale-free properties evolve in large complex networks through self … therefore efficient. At the same time, this efficiency feature puts scale-free networks at risk for becoming disconnected or …

This paper characterizes the set of equilibrium networks in the two-way flow model of network formation with small …, this set contains large- as well as small-diameter networks. For all benefit functions, the periphery-sponsored star is the … most stable. When the marginal benefits of information are constant, all non-star networks are equally stable. With …
