无标度随机图中团数的渐近性

Asymptotics for cliques in scale-free random graphs

Fraser Daly, Alastair Haig, Seva Shneer

AI总结:

本文研究Chung-Lu非齐次随机图模型中团数的渐近性,针对权重尾部概率为$h^{1-α}l(h)$($α>2$)的情形,给出了所有团大小及非整数$α$的完整渐近结果,并解释了整数$α$的差异及部分结果。

摘要:

在本文中,我们建立了Chung-Lu非齐次随机图模型中团数的期望值的渐近性(当图的大小趋于无穷大时)。在该模型中,每个顶点被赋予独立的权重,其尾部概率为$h^{1-α}l(h)$,其中$α>2$且$l$是一个缓变函数。每对顶点之间以与该对顶点权重乘积成比例的概率连边。我们给出了所有团大小以及所有非整数$α>2$情形的完整渐近性结果。我们还解释了整数$α$情形为何不同,并给出了该情形下渐近性的部分结果。

英文摘要:

In this paper we establish asymptotics (as the size of the graph grows to infinity) for the expected number of cliques in the Chung--Lu inhomogeneous random graph model in which vertices are assigned independent weights which have tail probabilities $h^{1-α}l(h)$, where $α>2$ and $l$ is a slowly varying function. Each pair of vertices is connected by an edge with a probability proportional to the product of the weights of those vertices. We present a complete set of asymptotics for all clique sizes and for all non-integer $α> 2$. We also explain why the case of an integer $α$ is different, and present partial results for the asymptotics in that case.
