Axelrod模型动力学中的发散时标

Divergent Time Scale in Axelrod Model Dynamics

F. Vazquez, S. Redner

摘要:

我们研究文化多样性的阿克塞尔罗德模型的演变。我们考虑一个简单的版本的模型,其中每个人的特点是由两个功能,其中每个可以假设q的可能性。在平均场描述中,我们发现在临界值q_c处,多样性的激活态和冻结态之间存在一个过渡。当q小于q_c时,相互作用伙伴之间的活动链接密度在时间上是非单调的,并且渐近接近稳态的时间尺度控制为(q-q_c)^{-1/2}。

英文摘要:

We study the evolution of the Axelrod model for cultural diversity. We consider a simple version of the model in which each individual is characterized by two features, each of which can assume q possibilities. Within a mean-field description, we find a transition at a critical value q_c between an active state of diversity and a frozen state. For q just below q_c, the density of active links between interaction partners is non-monotonic in time and the asymptotic approach to the steady state is controlled by a time scale that diverges as (q-q_c)^{-1/2}.
