Abstract

Recently, complex network has drawn considerable attentions as a basic tool to help us to understand a variety of phenomena in interdisciplinary fields such as biology, computer science, economics, mathematics, physics, and sociology. One of the empirical facts commonly appeared in empirical data of diverse fields is the heterogeneity in the connectivity distribution of each node, following a power-law distribution. This behavior is attractive as a new emerging behavior in complex systems. Here we review developments during last 3-4 years in this field, including structural properties of real-world networks and artificial models, the evolution of network topologies, dynamic problems on such complex networks.

Keywords: Complex systems, Network, Power-law
