网络中不同意见的共存

Coexistence of opposite opinions in a network with communities

R. Lambiotte, M. Ausloos

摘要:

多数规则适用于由两个耦合的随机网络组成的拓扑结构,从而模仿在社交网络中观察到的模块化结构。我们计算分析模型的渐近行为,并推导出一个相图,取决于随机意见翻转的频率和两个社区之间的互联性。结果表明,三个政权可能会发生:一个无序的政权,没有集体现象发生;一个对称的政权,在两个社区的节点达到相同的平均意见;一个不对称的政权,在每个社区的节点达到相反的平均意见。从非对称制度的对称制度的过渡被证明是不连续的。

英文摘要:

The Majority Rule is applied to a topology that consists of two coupled random networks, thereby mimicking the modular structure observed in social networks. We calculate analytically the asymptotic behaviour of the model and derive a phase diagram that depends on the frequency of random opinion flips and on the inter-connectivity between the two communities. It is shown that three regimes may take place: a disordered regime, where no collective phenomena takes place; a symmetric regime, where the nodes in both communities reach the same average opinion; an asymmetric regime, where the nodes in each community reach an opposite average opinion. The transition from the asymmetric regime to the symmetric regime is shown to be discontinuous.
