Multidimensional political polarization in online social networks
Antonio F. Peralta, Pedro Ramaciotti, János Kertész +1
Political polarization in online social platforms is a rapidly growing phenomenon worldwide. Despite their relevance to modern-day politics, the structure and dynamics of polarized…
Analytical and numerical treatment of continuous ageing in the voter model
Joseph W. Baron, Antonio F. Peralta, Tobias Galla +1
The conventional voter model is modified so that an agent's switching rate depends on the `age' of the agent, that is, the time since the agent last switched opinion. In contrast t…
Opinion dynamics in social networks: From models to data
Antonio F. Peralta, János Kertész, Gerardo Iñiguez
Opinions are an integral part of how we perceive the world and each other. They shape collective action, playing a role in democratic processes, the evolution of norms, and cultura…
Opinion formation on social networks with algorithmic bias: Dynamics and bias imbalance
Antonio F. Peralta, János Kertész, Gerardo Iñiguez
We investigate opinion dynamics and information spreading on networks under the influence of content filtering technologies. The filtering mechanism, present in many online social…
The effect of algorithmic bias and network structure on coexistence, consensus, and polarization of opinions
Antonio F. Peralta, Matteo Neri, János Kertész +1
Individuals of modern societies share ideas and participate in collective processes within a pervasive, variable, and mostly hidden ecosystem of content filtering technologies that…
Binary-state dynamics on complex networks: Stochastic pair approximation and beyond
Antonio F. Peralta, Raul Toral
Theoretical approaches to binary-state models on complex networks are generally restricted to infinite size systems, where a set of non-linear deterministic equations is assumed to…
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…
Reduction from non-Markovian to Markovian dynamics: The case of aging in the noisy-voter model
Antonio F. Peralta, Nagi Khalil, Raul Toral
We study memory dependent binary-state dynamics, focusing on the noisy-voter model. This is a non-Markovian process if we consider the set of binary states of the population as the…
Ordering dynamics in the voter model with aging
Antonio F. Peralta, Nagi Khalil, Raul Toral
The voter model with memory-dependent dynamics is theoretically and numerically studied at the mean-field level. The `internal age', or time an individual spends holding the same s…
Herding and idiosyncratic choices: Nonlinearity and aging-induced transitions in the noisy voter model
Oriol Artime, Adrián Carro, Antonio F. Peralta +3
We consider the herding to non-herding transition caused by idiosyncratic choices or imperfect imitation in the context of the Kirman Model for financial markets, or equivalently t…
Aging-induced continuous phase transition
Oriol Artime, Antonio F. Peralta, Raúl Toral +2
Aging is considered as the property of the elements of a system to be less prone to change states as they get older. We incorporate aging into the noisy voter model, a stochastic m…
Stochastic pair approximation treatment of the noisy voter model
A. F. Peralta, A. Carro, M. San Miguel +1
We present a full stochastic description of the pair approximation scheme to study binary-state dynamics on heterogeneous networks. Within this general approach, we obtain a set of…
Analytical and numerical study of the non-linear noisy voter model on complex networks
A. F. Peralta, A. Carro, M. San Miguel +1
We study the noisy voter model using a specific non-linear dependence of the rates that takes into account collective interaction between individuals. The resulting model is solved…
