A Multidimensional Bounded-Confidence Opinion Dynamics Model with EPOs and an Opinion Leader
This paper studies the evolution of expressed and private opinions(EPOs)on multiple topics under group pressure in a social network with an opinion leader involved.To characterize the influence of interactions between different individuals'EPOs on multiple topics,a new multidimensional bounded-confidence opinion dynamics model is proposed.In this model,a coupling matrix of multi-issues dependence structure(MiDS)is introduced as a homogeneous"belief system"for all individuals to recognize the inherent relationship between these specific topics.Sufficient conditions for the convergence of the opinion in our model are given by theoretical analysis using graph theory and the regularity of the matrix.Simulations on the model with two types of MiDS,independent topics and interdependent topics,are performed and the results verify the correctness of the conclusion.
