Phase transitions, characterized by abrupt shifts between macroscopic patterns of organization, are ubiquitous in complex systems. Despite considerable research in the physical and…
Opinion Dynamics on Networks under Correlated Disordered External Perturbations
Marlon Ramos, Marcus A. M. de Aguiar, Dan Braha
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…
