Consequences of nonconformist behaviors in a continuous opinion model
- Computer ScienceArXiv
- 2016
Investigation of opinion formation in a kinetic exchange opinion model, where opinions are represented by numbers in the real interval and agents are typified by the individual degree of conviction about the opinion that they support, emphasizes the emergence of extreme opinions.
Noise and disorder: phase transitions and universality in a model of opinion formation
- Computer Science
- 2015
It is found that the critical exponents are universal over the order-disorder frontier, presenting the same universality class of the mean-field Ising model.
Non-equilibrium dynamics in a three state opinion formation model with stochastic extreme switches
- Physics

We investigate the nonequilibrium dynamics of a three-state kinetic exchange model of opinion formation, where switches between extreme states are possible, depending on the value of a parameter q.…
Opinion formation models with extreme switches and disorder: critical behaviour and dynamics
- Physics

In a three state kinetic exchange opinion formation model, the effect of extreme switches was considered in a recent paper. In the present work, we study the same model with disorder. Here disorder…

The universality class of the phase transitions in the model is found to be same as Ising model in the respective dimensions.
Phase transitions in the q-voter model with noise on a duplex clique.
- MathematicsPhysical review. E, Statistical, nonlinear, and soft matter physics
- 2015
A nonlinear q-voter model with stochastic noise, interpreted in the social context as independence, on a duplex network is studied and three methods of transferring the model from a mono- to a multiplex network are proposed.
Generalized Independence in the q-Voter Model: How Do Parameters Influence the Phase Transition?
- PhysicsEntropy

The role of flexibility, which can be understood as an amount of variability associated with an independent behavior, as well as the role of the average network degree in shaping the character of the phase transition are determined.
Long route to consensus: Two-stage coarsening in a binary choice voting model.
- MathematicsPhysical review. E
- 2020
It is shown in a kinetic exchange opinion model considered on L×L square lattices, that while such frozen states could be avoided, an exponentially slow approach to consensus is manifested.
Consensus formation in continuous opinion dynamics on quasiperiodic lattices

We propose a minimal multiagent model for the collective dynamics of opinion formation in the society by modifying kinetic exchange dynamics studied in the context of income, money, or wealth…
Van Kampen's expansion approach in an opinion formation model

Abstract.
We analyze a simple opinion formation model consisting of two
parties, A and B, and a group I, of undecided agents. We
assume that the supporters of parties A and B do not interact
among…
Phase transitions in a two-parameter model of opinion dynamics with random kinetic exchanges.

A phase boundary given by λ=1-μ/2 is obtained separating the symmetric and symmetry broken phases: the effect of the influencing term enhances the possibility of reaching a consensus in the society.
Effects of agents' mobility on opinion spreading in Sznajd model

Abstract
Under synchronous updating and allowing the agents to move
in the lattice or underlying network, we find that the Sznajd model always
reaches a consensus as a steady state, – because agent…
Phase transitions in the q-voter model with two types of stochastic driving.

- 2012
The concept of social temperature is clarified and it is shown that different types of noise may lead to qualitatively different emergent properties and that in the model with anticonformity the critical value of noise increases with parameter q, whereas in the models with independence the criticalvalue of noise decreases with q.
Anticonformity or Independence?—Insights from Statistical Physics

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, i.e. in the society. The inspiration…

We examine the ultimate fate of individual opinions in a socially interacting population of leftists, centrists and rightists. In an elemental interaction between agents, a centrist and a leftist can…
