Noisy kinetic-exchange opinion model with aging
Allan R. Vieira, Jaume Llabrés, Raúl Toral +1
We study the critical behavior of a noisy kinetic opinion model subject to resilience to change depending on aging, defined as the time spent on the current opinion state. In this…
Controlling the average degree in random power-law networks
Allan Vieira, Judson Moura, Celia Anteneodo
We describe a procedure that allows continuously tuning the average degree of uncorrelated networks with power-law degree distribution . Inn order to do t…
Nonlinear redistribution of wealth from a stochastic approach
Hugo Lima, Allan R. Vieira, Celia Anteneodo
We investigate the effect of applying nonlinear redistributive taxes to the yard-sale dynamics of assets. An amount of money is collected from each individual (tax) and distributed…
Pair approximation for the noisy threshold -voter model
A. R. Vieira, Antonio F. Peralta, Raul Toral +2
In the standard -voter model, a given agent can change its opinion only if there is a full consensus of the opposite opinion within a group of influence of size . A more real…
Imperfect bifurcations in opinion dynamics under external fields
Francisco Freitas, Allan R. Vieira, Celia Anteneodo
We investigate, through a kinetic-exchange model, the impact that an external field, like advertising and propaganda, has on opinion dynamics. We address the situations where two o…
Threshold -voter model
Allan R. Vieira, Celia Anteneodo
We introduce the threshold -voter opinion dynamics where an agent, facing a binary choice, can change its mind when at least amongst neighbors share the opposite opini…
Noise-induced absorbing phase transition in a model of opinion formation
Allan R. Vieira, Nuno Crokidakis
In this work we study a 3-state (, , ) opinion model in the presence of noise and disorder. We consider pairwise competitive interactions, with a fraction of those i…
Consequences of nonconformist behaviors in a continuous opinion model
Allan R. Vieira, Celia Anteneodo, Nuno Crokidakis
We investigate opinion formation in a kinetic exchange opinion model, where opinions are represented by numbers in the real interval and agents are typified by the individ…
Phase transitions in the majority-vote model with two types of noises
Allan R. Vieira, Nuno Crokidakis
In this work we study the majority-vote model with the presence of two distinc noises. The first one is the usual noise , that represents the probability that a given agent foll…
