Opinion dynamics have attracted the interest of researchers from different fields. Local
interactions among individuals create interesting dynamics for the system as a whole. Such …

Recently, social phenomena have received a lot of attention not only from social scientists,
but also from physicists, mathematicians and computer scientists, in the emerging …

This review presents an overview of the current research in kinetic exchange models for
opinion formation in a society. The review begins with a brief introduction to previous models …

Agent-based models are now largely adopted to describe how opinions emerge in a group
of people. This survey provides an analysis of the literature on the subject, highlighting the …

We investigate the emergence of extreme opinion trends in society by employing statistical
physics modeling and analysis on polls that inquire about a wide range of issues such as …

In recent years, it has been increasing evidence that lognormal distributions are widespread
in physical and biological sciences, as well as in various phenomena of economics and …

In this work we study opinion formation on a fully connected population participating of a
public debate with two distinct choices, where the agents may adopt three different attitudes …

We introduce the threshold q-voter opinion dynamics where an agent, facing a binary
choice, can change its mind when at least q 0 among q neighbors share the opposite …

Quantifying the eigenvalue spectra of large random matrices allows one to understand the
factors that contribute to the stability of dynamical systems with many interacting …

We analyze the critical behavior of a class of discrete opinion models in the presence of
disorder. Within this class, each agent opinion takes a discrete value (±1 or 0) and its time …
