Statistical Mechanics of Complex Networks: 625: Pastor Satorras

A complex network is a powerful tool to characterize several different types of natural and man-made systems, such as brain networks [1] , [2] , computer science [3] , [4] , Internet topology [5] , [6] , and social networks [7] , [8] . Complex networks describe a wide range of systems in nature and society. Frequently cited examples include the cell, a network of chemicals linked by chemical reactions, and the Internet, a network of routers and computers connected by physical links. The purpose of this article is to review each of these modeling efforts, focusing on the statistical mechanics of complex networks.

Reka Albert, Albert-Laszlo Barabasi Reviews of Modern Physics 74, 47 (2002) cond-mat/0106096 •The structure and function of complex networks. M. E. J. Newman, SIAM Review 45, 167-256 (2003) Models of this type play the same role in the study of networks as is played by the Boltzmann distribution in classical statistical mechanics; they offer the best prediction of network properties subject to the constraints imposed by a given set of observations. In this thesis, we would like to present a consistent approach to complex networks based on statistical mechanics, with the central role played by the concept of statistical ensemble of networks. We show how to construct such a theory and present some practical problems where it can be applied.

Our main goal is to present the theoretical developments in parallel with the empirical data that initiated and support the various models and theoretical tools. Many of these systems form complex networks whose nodes are the elements of the system and edges represent the interactions between them. Traditionally complex networks have been described by the random graph theory founded in 1959 by Paul Erdo&huml;s and Alfréd Rényi.

Boolean models are faster to simulate, but tend to be farther removed from the biology, and can be misleading even in some simple cases (Guet et al. 2002).

While traditionally these systems have been modeled as random graphs, it is increasingly recognized that the topology and evolution of real While traditionally these systems have been modeled as random graphs, it is increasingly recognized that the topology and evolution of real networks are governed by robust organizing principles. This article reviews the recent advances in the field of complex networks, focusing on the statistical mechanics of network topology and dynamics.
