Threshold model of language competition including the bilingual state
Mikhail V. Tamm, Els Heinsalu, Stefano Scialla +1
We propose a threshold model of language competition which includes intermediate bilingual state. The model is based on the Minett-Wang model but through the introduction of thresh…
The role of zealots in the spread of linguistic traits
Vivian Dornelas, Celia Anteneodo, Renan Nunes +2
We investigate the diffusion of linguistic innovations on a fully connected network in order to understand the emergence of linguistic diversity. We employ an agent-based dynamics…
Effect of diversity distribution symmetry on global oscillations of networks of excitable units
Stefano Scialla, Marco Patriarca, Els Heinsalu +2
We investigate the role of the degree of symmetry of the diversity distribution in shaping the collective dynamics of networks of coupled excitable units modeled by FitzHugh-Nagumo…
Dynamical equivalence between resonant translocation of a polymer chain and diversity-induced resonance
Marco Patriarca, Stefano Scialla, Els Heinsalu +2
Networks of heterogeneous oscillators are often seen to display collective synchronized oscillations, even when single elements of the network do not oscillate in isolation. It has…
Learning thresholds lead to stable language coexistence
Mikhail V. Tamm, Els Heinsalu, Stefano Scialla +1
We introduce a language competition model that is based on the Abrams-Strogatz model and incorporates the effects of memory and learning in the language shift dynamics. On a coarse…
