Usually, opinion formation models assume that individuals have an opinion about a given topic which can change due to interactions with others. However, individuals can have different opinions on different topics and ...

This paper presents a development of the so-called kinetic theory for active particles to the modeling of living, hence complex, systems localized in networks. The overall system is viewed as a network of interacting nodes, ...

Predicting different forms of collective behavior in human populations, as the outcome of individual attitudes and their mutual influence, is a question of major interest in social sciences. In particular, processes of ...

In this work we introduce the idea of fitness in the context of opinion dynamics. We obtain the hydrodynamic equations for a kinetic model including the attractiveness or strength of each opinion, and we find a conserved ...

The research at issue refers to the images study and the critical public opinion formation in the teaching formation process in a course of Pedagogy at URI Santiago/RS/Brazil. In the first part of the research it was ...

We propose a general non-linear analytical framework to study the evolution of the opinion state of a population of moving individuals. This novel scheme allows us to study a broad range of social phenomena, like, for ...

Opinion formation and disease spreading are among the most studied dynamical processes on complex networks. In real societies, it is expected that these two processes depend on and affect each other. However, little is ...

In this work we study the formation of consensus in homogeneous and heterogeneous populations, and the effect of attractiveness or fitness of the opinions. We derive the corresponding kinetic equations, analyze the long ...
