Social influence with recurrent mobility and multiple options — •Attila Szilva1 and Jérôme Michaud2 — 1Department of Physics and Astronomy, University of Uppsala, 752 37 Uppsala, Sweden — 2Department of Physics and Astronomy, University of Uppsala, 752 37 Uppsala, Sweden and Department of Sociology, University of Uppsala, 751 20 Uppsala, Sweden
In this paper, we discuss the possible generalizations of the social influence with recurrent mobility (SIRM) model [Phys. Rev. Lett. 112, 158701 (2014)]. Although the SIRM model worked approximately satisfying when U.S. election was modeled, it has its limits: it has been developed only for two-party systems and can lead to unphysical behavior when one of the parties has extreme vote share close to 0 or 1. We propose here generalizations to the SIRM model by its extension for multiparty systems that are mathematically well-posed in case of extreme vote shares, too, by handling the noise term in a different way. In addition, we show that our method opens alternative applications for the study of elections by using an alternative calibration procedure and makes it possible to analyze the influence of the *free will* (creating a new party) and other local effects for different commuting network topologies.
