In this paper, we propose a Boltzmann-type kinetic description of opinion formation on social networks, which takes into account a general connectivity distribution of the individuals. We consider opinion exchange processes inspired by the Sznajd model and related simplifications but we do not assume that individuals interact on a regular lattice. Instead, we describe the structure of the social network statistically, assuming that the number of contacts of a given individual determines the…

Kinetic exchange models of societies and economies
The statistical nature of collective human behaviour in a society is a topic of broad current interest. From formation of consensus through exchange of ideas, distributing wealth through exchanges of

Opinion dynamics over complex networks: kinetic modeling and numerical methods
TLDR
A kinetic description of the agents' distribution over the evolving network is considered which combines an opinion update based on binary interactions between agents with a dynamic creation and removal process of new connections.

TLDR
It will be demonstrated how a certain form of kinetic equations can be obtained to describe such interactions at a mesoscopic level and moreover obtain macroscopic models from monokinetics solutions of those.
Discretized kinetic theory on scale-free networks
TLDR
This paper equips the model discussed in [1, 2] with a network structure based on a system of n differential equations of the kinetic discretized-Boltzmann kind, and investigates numerically the dependence of the detailed and marginal equilibrium distributions on the initial conditions and on the exponent q.
A two-layer model for coevolving opinion dynamics and collective decision-making in complex social systems
TLDR
Light is shed on the role of the coupling between opinion dynamics and decision-making, and of the network structure, in shaping the emergence of complex collective behavior in social systems through the establishment of analytical conditions and Monte Carlo numerical simulations.
Opinion modeling on social media and marketing aspects
TLDR
Numerical experiments on the underlying kinetic models show a good qualitative agreement with some measured trends of hashtags on social media websites and illustrate how companies can take advantage of the network structure to obtain at best the advertisement of their products.
Opinion Dynamics and Learning in Social Networks
TLDR
An overview of recent research on belief and opinion dynamics in social networks is provided and the implications of the form of learning, sources of information, and the structure of social networks are discussed.
Analytical results for the Sznajd model of opinion formation
Abstract.The Sznajd model, which describes opinion formation and social influence, is treated analytically on a complete graph. We prove the existence of the phase transition in the original
Rigorous Results for the Distribution of Money on Connected Graphs
This paper is concerned with general spatially explicit versions of three stochastic models for the dynamics of money that have been introduced and studied numerically by statistical physicists: the
Random graph models of social networks
TLDR
It is found that in some cases, the models are in remarkable agreement with the data, whereas in others the agreement is poorer, perhaps indicating the presence of additional social structure in the network that is not captured by the random graph.
Rigorous Proof of the Boltzmann–Gibbs Distribution of Money on Connected Graphs
Models in econophysics, i.e., the emerging field of statistical physics that applies the main concepts of traditional physics to economics, typically consist of large systems of economic agents who
