Population Fragmentation and Party Dynamics in an Evolutionary Political Game

Abstract

We examine kinetic symmetry breaking phenomena in an evolutionary political game in which voters, inhabiting a multidimensional ideological space, cast ballots via selection mechanisms subject to the competing forces of conformity and dissent. Our understanding of the spatiotemporally complex population dynamics is informed by a system of nonlinear replicator equations, discrete deterministic cousin of the original stochastic Seceder Model.
