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…
Impact of network randomness on multiple opinion dynamics
Vivian Dornelas, Marlon Ramos, Celia Anteneodo
People often face the challenge of choosing among different options with similar attractiveness. To study the distribution of preferences that emerge in such situations, a useful a…
Registering the evolutionary history in individual-based models of speciation
Carolina L. N. Costa, Flavia M. D. Marquitti, S. Ivan Perez +3
Understanding the emergence of biodiversity patterns in nature is a central problem in biology. Theoretical models of speciation have addressed this question in the macroecological…
Role of the plurality rule in multiple choices
Angelo M. Calvão, Marlon Ramos, Celia Anteneodo
People are often challenged to select one among several alternatives. This situation is present not only in decisions about complex issues, e.g., political or academic choices, but…
How does public opinion become extreme?
Marlon Ramos, Jia Shao, Saulo D. S. Reis +4
We investigate the emergence of extreme opinion trends in society by employing statistical physics modeling and analysis on polls that inquire about a wide range of issues such as…
Information spreading with aging in heterogeneous populations
Marlon Ramos, Nuno Crokidakis, Celia Anteneodo
We study the critical properties of a model of information spreading based on the SIS epidemic model. Spreading rates decay with time, as ruled by two parameters, and , that…
Random degree-degree correlated networks
Marlon Ramos, Celia Anteneodo
Correlations may affect propagation processes on complex networks. To analyze their effect, it is useful to build ensembles of networks constrained to have a given value of a struc…
