Abstract
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 $$R_n\rightarrow \infty$$ 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 and 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.
