Statistical physics has proven to be a fruitful framework to describe phenomena outside the
realm of traditional physics. Recent years have witnessed an attempt by physicists to study …

We review a series of models of sociophysics introduced by Galam and Galam et al. in the
last 25 years. The models are divided into five different classes, which deal respectively with …

This book discusses the study and analysis of the physical aspects of social systems and
models, inspired by the analogy with familiar models of physical systems and possible …

We study the effect of inflexible agents on two state opinion dynamics. The model operates
via repeated local updates of random grou** of agents. While floater agents do eventually …

We introduce a nonlinear variant of the voter model, the q-voter model, in which q neighbors
(with possible repetition) are consulted for a voter to change opinion. If the q neighbors …

The aim of this paper is to examine how different types of social influence, introduced on the
microscopic (individual) level, manifest on the macroscopic level, ie in the society. The …

In recent decades, a number of centrality metrics describing network properties of nodes
have been proposed to rank the importance of nodes. In order to understand the correlations …

Social influence plays an important role in human behavior and decisions. Sources of
influence can be divided as external, which are independent of social context, or as …

The book requires only rudimentary physics knowledge but ability to program computers
creatively and to keep the mind open to simple and not so simple models, based in …

We propose a “nonconsensus” opinion model that allows for stable coexistence of two
opinions by forming clusters of agents holding the same opinion. We study this …
