具有独立性的动态交换意见模型的相变

Phase transition in kinetic exchange opinion models with independence

Nuno Crokidakis

摘要:

本文研究了具有独立性的三态($+1$,$-1$,$0$)意见模型的临界行为.每个代理都有一个概率$q$作为独立的,即,他/她可以独立于其他代理人的意见来选择他/她的意见。另一方面,在互补概率$1-q$的情况下,代理通过动力学交换与随机选择的个体相互作用。我们的分析和数值计算结果表明,独立机制作为一个噪音,诱导在临界点$q_{c}$,取决于个人的灵活性的有序-无序转变。对于这种灵活性的一个特殊值,该系统经历了一个过渡到吸收状态与所有意见$0$。

英文摘要:

In this work we study the critical behavior of a three-state ($+1$, $-1$, $0$) opinion model with independence. Each agent has a probability $q$ to act as independent, i.e., he/she can choose his/her opinion independently of the opinions of the other agents. On the other hand, with the complementary probability $1-q$ the agent interacts with a randomly chosen individual through a kinetic exchange. Our analytical and numerical results show that the independence mechanism acts as a noise that induces an order-disorder transition at critical points $q_{c}$ that depend on the individuals' flexibility. For a special value of this flexibility the system undergoes a transition to an absorbing state with all opinions $0$.
