网络上的社会平衡:友谊与包容的动力学

Social Balance on Networks: The Dynamics of Friendship and Enmity

T. Antal, P. L. Krapivsky, S. Redner

摘要:

当友好关系和不友好关系同时存在时,社交网络是如何演变的?在这里,我们提出了一个简单的动态社交网络,其中关系的意义可以改变,以消除不平衡的三元组-关系三角形,包含1或3个不友好的链接。在这个动力学中,在一个不平衡的三和弦中,一个友好的链接变成了不友好的链接,反之亦然,以使三和弦平衡。随着网络友好程度的改变,这样的网络经历了一个动态的相变,从稳定状态到“乌托邦”--所有的友好链接。讨论了长时间动力学和相变的基本特征。

英文摘要:

How do social networks evolve when both friendly and unfriendly relations exist? Here we propose a simple dynamics for social networks in which the sense of a relationship can change so as to eliminate imbalanced triads--relationship triangles that contains 1 or 3 unfriendly links. In this dynamics, a friendly link changes to unfriendly or vice versa in an imbalanced triad to make the triad balanced. Such networks undergo a dynamic phase transition from a steady state to "utopia"--all friendly links--as the amount of network friendliness is changed. Basic features of the long-time dynamics and the phase transition are discussed.
