Consensus and diversity in multi-state noisy voter models
Francisco Herrerías-Azcué, Tobias Galla
We study a variant of the voter model with multiple opinions; individuals can imitate each other and also change their opinion randomly in mutation events. We focus on the case of…
Motion, fixation probability and the choice of an evolutionary process
Francisco Herrerías-Azcué, Vicente Pérez-Muñuzuri, Tobias Galla
Different evolutionary models are known to make disparate predictions for the success of an invading mutant in some situations. For example, some evolutionary mechanics lead to amp…
Fast flowing populations are not well mixed
Francisco Herrerías-Azcué, Vicente Pérez-Muñuzuri, Tobias Galla
In evolutionary dynamics, well-mixed populations are almost always associated with all-to-all interactions; mathematical models are based on complete graphs. In most cases, these m…
The effects of heterogeneity on stochastic cycles in epidemics
Francisco Herrerías-Azcué, Tobias Galla
Models of biological processes are often subject to different sources of noise. Developing an understanding of the combined effects of different types of uncertainty is an open cha…
