Mass media and repulsive interactions in continuous-opinion dynamics

TV Martins, M Pineda, R Toral - Europhysics Letters, 2010 - iopscience.iop.org
This letter focuses on the effect of repulsive interactions on the adoption of an external
message in an opinion model. With a simple change in the rules, we modify the Deffuant et …

Breaking the symmetry neutralizes the extremization under the repulsion and higher order interactions

C Huang, H Bian, W Han - Chaos, Solitons & Fractals, 2024 - Elsevier
In this work, the opinion dynamics with both biased assimilation and repulsion mechanisms
on hypergraphs is investigated, and the fraction of extreme agents is the focus. In the …

Opinion dynamics with disagreement and modulated information

A Sîrbu, V Loreto, VDP Servedio, F Tria - Journal of Statistical Physics, 2013 - Springer
Opinion dynamics concerns social processes through which populations or groups of
