A Hybrid Opinion Formation and Polarization Model
Entropy, 2022 The last decade has witnessed a great number of opinion formation models that depict the evolution of opinions within a social group and make predictions about the evolution process. In the traditional formulation of opinion evolution such as the DeGroot

Dynamics of opinion expression [PDF]
Physical Review E, 2020 Modeling efforts in opinion dynamics have to a large extent ignored that opinion exchange between individuals can also have an effect on how willing they are to express their opinion publicly. Here, we introduce a model of public opinion expression.

Characterizing Controversiality of Topics Utilizing Eccentricity of Opinions
Northeast Journal of Complex Systems, 2023 Access to abundant biased information in echo chambers and social bubbles often intensifies opinions to the extremes. The extremization of opinions results in several topics becoming controversial.

Opinion Dynamics on Discourse Sheaves [PDF]
SIAM Journal on Applied Mathematics, 2021 We introduce a novel class of Laplacians and diffusion dynamics on discourse sheaves as a model for network dynamics, with application to opinion dynamics on social networks. These sheaves are algebraic data structures tethered to a network (or more general space) that can represent various modes of communication, including selective opinion modulation

Dynamical affinity in opinion dynamics modeling [PDF]
Physical Review E, 2007 We here propose a model to simulate the process of opinion formation, which accounts for the mutual affinity between interacting agents. Opinion and affinity evolve self-consistently, manifesting a highly non trivial interplay. A continuous transition is found between single and multiple opinion states.

Opinion dynamics on tie-decay networks
Physical Review Research, 2021 In social networks, interaction patterns typically change over time. We study opinion dynamics on tie-decay networks in which tie strength increases instantaneously when there is an interaction and decays exponentially between interactions. Specifically,

Opinion dynamics in finance and business: a literature review and research opportunities
Financial Innovation, 2021 Opinion dynamics is an opinion evolution process of a group of agents, where the final opinion distribution tends to three stable states: consensus, polarization, and fragmentation. At present, the opinion dynamics models have been extensively studied in

Opinion Evolution in Divided Community
Entropy, 2022 Our agent-based model of opinion dynamics concerns the current vast divisions in modern societies. It examines the process of social polarization, understood here as the partition of a community into two opposing groups with contradictory opinions.

On Symmetric Continuum Opinion Dynamics [PDF]
SIAM Journal on Control and Optimization, 2016 This paper investigates the asymptotic behavior of some common opinion dynamic models in a continuum of agents. We show that as long as the interactions among the agents are symmetric, the distribution of the agents' opinion converges. We also investigate whether convergence occurs in a stronger sense than merely in distribution, namely, whether the ...

The Sound of Silence: Minorities, Abstention and Democracy
Entropy, 2021 Despite the existence of an extensive literature, no definitive conclusion seems to emerge on the extent to which minorities are guaranteed by democratic rules in political systems.
