DOI: 10.1007/s10955-018-2135-5
Abstract: We study an influence network of voters subjected to correlated disordered external perturbations, and solve the dynamical equations exactly for fully connected networks. The model has a critical phase transition between disordered unimodal and ordered… read more here.

DOI: 10.1016/j.jpubeco.2020.104188
Abstract: Ranking algorithms are the information gatekeepers of the Internet era. We develop a stylized framework to study the effects of ranking algorithms on opinion dynamics. We consider rankings that depend on popularity and on personalization.… read more here.

DOI: 10.1016/j.physa.2018.03.077
Abstract: Abstract We investigate an agent-based model of opinion dynamics with two types of social response: conformity and independence. Conformity is introduced to the model analogously as in the Sznajd model or q -voter model, which… read more here.

DOI: 10.1017/jpr.2020.113
Abstract: Abstract This paper introduces a non-linear and continuous-time opinion dynamics model with additive noise and state-dependent interaction rates between agents. The model features interaction rates which are proportional to a negative power of the opinion… read more here.

DOI: 10.1063/5.0004787
Abstract: Motivated by the literature on opinion dynamics and evolutionary game theory, we propose a novel mathematical framework to model the intertwined coevolution of opinions and decision-making in a complex social system. In the proposed framework,… read more here.

DOI: 10.1063/5.0007523
Abstract: It is known that individual opinions on different policy issues often align to a dominant ideological dimension (e.g., left vs right) and become increasingly polarized. We provide an agent-based model that reproduces alignment and polarization… read more here.

Generalized mean-field approximation for the Deffuant opinion dynamics model on networks.

DOI: 10.1103/physreve.103.012314
Abstract: When the interactions of agents on a network are assumed to follow the Deffuant opinion dynamics model, the outcomes are known to depend on the structure of the underlying network. This behavior cannot be captured… read more here.

DOI: 10.1109/access.2022.3160718
Abstract: In this paper, the opinion dynamics model with antagonistic (competitive) relationship, multiple interdependent topics and the stubborn individuals is investigated. Different from the classical Friedkin-Johnsen (FJ) model, in our model, antagonistic and cooperative relationships are… read more here.

DOI: 10.1109/access.2022.3218719
Abstract: When controversial products are introduced, effective promotion efforts and eventual public acceptance require consideration of multiple factors such as existing social network structures, numbers of pioneers and their locations, and appropriate methods for product information… read more here.

DOI: 10.1109/jsyst.2022.3205724
Abstract: Persuasion exists in every aspect of social life. It is important to understand how persuasion works and how strong it is. In this article, we improve the classic Hegselmann–Krause model, one of the most famous… read more here.

Nonlinear Opinion Dynamics with Tunable Sensitivity

DOI: 10.1109/tac.2022.3159527
Abstract: We propose a continuous-time multi-option nonlinear generalization of classical linear weighted-average opinion dynamics. Nonlinearity is introduced by saturating opinion exchanges, and this is enough to enable a significantly greater range of opinion-forming behaviors with our… read more here.
