摘要
In traditional models of opinion dynamics, each 智能體 in a 網絡 has an opinion and changes in opinions arise from pairwise (i.e., dyadic) interactions between 智能體s. However, in many situations, groups of individuals possess a collective opinion that can differ from the opinions of their constituent individuals. In this paper, we study the effects of group opinions on opinion dynamics. We formulate a hypergraph model in which both individual 智能體s and groups of three 智能體s have opinions, and we examine how opinions evolve through both dyadic interactions and group memberships. We find for some parameter values that the presence of group opinions can lead to oscillatory and excitable opinion dynamics. In the oscillatory regime, the mean opinion of the 智能體s in a 網絡 has self-sustained oscillations.
