尾部贝蒂数的泛函强大数律

Functional strong law of large numbers for Betti numbers in the tail

Takashi Owada, Zifu Wei

摘要:

研究了概率分布尾部拓扑复杂性的分层结构。建立了半径为$R_n$的开球外几何复形的代数拓扑的基本量词贝蒂数的泛函强大数律,使得当样本量$n$增加时,$R_n\to\infty$.所得到的大数定律的性质是由概率密度的衰减率决定的。它特别取决于密度的尾部是以规则变化的速率衰减还是以指数衰减的速率衰减。极限定理的性质还取决于$R_n$发散的速度。特别是,如果$R_n$发散足够慢,在大数定律的限制功能是至关重要的影响,出现任意大的连接组件支持拓扑循环的限制。

英文摘要:

The objective of this paper is to investigate the layered structure of topological complexity in the tail of a probability distribution. We establish the functional strong law of large numbers for Betti numbers, a basic quantifier of algebraic topology, of a geometric complex outside an open ball of radius $R_n$, such that $R_n\to\infty$ as the sample size $n$ increases. The nature of the obtained law of large numbers is determined by the decay rate of a probability density. It especially depends on whether the tail of a density decays at a regularly varying rate or an exponentially decaying rate. The nature of the limit theorem depends also on how rapidly $R_n$ diverges. In particular, if $R_n$ diverges sufficiently slowly, the limiting function in the law of large numbers is crucially affected by the emergence of arbitrarily large connected components supporting topological cycles in the limit.
