有向小世界网络上的观点动力学

Opinion dynamics on directed small-world networks

Luo-Luo Jiang, Da-Yin Hua, Jun-Fang Zhu, Bing-Hong Wang, Tao Zhou

摘要:

本文研究了在有向小世界社会网络中,自我肯定对舆论形成的影响。系统呈现出从共识状态到意见共存的无序状态的非平衡相变。动力学行为对长程相互作用的密度和自我肯定的强度非常敏感。当远程交互稀疏且个体一般不坚持自己的观点时,系统会出现连续的相变;当自我肯定强度高且远程交互密集时,系统不会出现相变。在这两种极端情况之间,系统经历不连续的相变。

英文摘要:

In this paper, we investigate the self-affirmation effect on formation of public opinion in a directed small-world social network. The system presents a non-equilibrium phase transition from a consensus state to a disordered state with coexistence of opinions. The dynamical behaviors are very sensitive to the density of long-range interactions and the strength of self-affirmation. When the long-range interactions are sparse and individual generally does not insist on his/her opinion, the system will display a continuous phase transition, in the opposite case with high self-affirmation strength and dense long-range interactions, the system does not display a phase transition. Between those two extreme cases, the system undergoes a discontinuous phase transition.
