将复杂网络连接到非加性熵

Connecting complex networks to nonadditive entropies

R. M. de Oliveira, Samuraí Brito, L. R. da Silva, Constantino Tsallis

摘要:

玻尔兹曼-吉布斯统计力学可以令人满意地应用于许多系统。然而,对于一般涉及强时空纠缠的复杂系统,它失败了。它的推广基于非加性$q$ -熵充分处理了广泛的一类这样的系统。我们在这里表明,规模不变网络属于这一类。我们数值研究了一个$d$维的地理位置网络与加权链接,并展示其“能量”分布在其准稳态每个站点。我们的研究结果强烈建议之间的对应关系的随机几何问题和一类热问题的广义热统计。Boltzmann-Gibbs指数因子一般由其$q$ -推广来代替,并且当非局部效应消失时在$q=1$极限中恢复。目前的联系应该在这两个研究领域的交叉施肥实验。

英文摘要:

Boltzmann-Gibbs statistical mechanics applies satisfactorily to a plethora of systems. It fails however for complex systems generically involving strong space-time entanglement. Its generalization based on nonadditive $q$-entropies adequately handles a wide class of such systems. We show here that scale-invariant networks belong to this class. We numerically study a $d$-dimensional geographically located network with weighted links and exhibit its 'energy' distribution per site at its quasi-stationary state. Our results strongly suggest a correspondence between the random geometric problem and a class of thermal problems within the generalised thermostatistics. The Boltzmann-Gibbs exponential factor is generically substituted by its $q$-generalisation, and is recovered in the $q=1$ limit when the nonlocal effects fade away. The present connection should cross-fertilise experiments in both research areas.
