偏好连接(PA)模型是一类常见的图模型,它被用来解释为什么幂律分布出现在真实的网络数据的度序列中。在现实世界网络的其他属性中,它们通常具有非平凡的聚类系数,这是由于大量的三角形以及本征值谱中的幂律。虽然在特定的功率放大器结构中存在三角形功率放大器模型和特征值幂律,但没有结果表明现有的结构同时具有这两种模型。在这篇文章中,我们提出了一个特定的三角形广义偏好依恋模型,通过构造,具有非平凡的聚类。我们进一步证明了该模型在度分布和本征值谱上都具有幂律。
Preferential attachment (PA) models are a common class of graph models which have been used to explain why power-law distributions appear in the degree sequences of real network data. Among other properties of real-world networks, they commonly have non-trivial clustering coefficients due to an abundance of triangles as well as power laws in the eigenvalue spectra. Although there are triangle PA models and eigenvalue power laws in specific PA constructions, there are no results that existing constructions have both. In this article, we present a specific Triangle Generalized Preferential Attachment Model that, by construction, has non-trivial clustering. We further prove that this model has a power law in both the degree distribution and eigenvalue spectra.
