Random simplicial complexes: models and phenomena

O Bobrowski, D Krioukov - Higher-Order Systems, 2022 - Springer
We review a collection of models of random simplicial complexes together with some of the
most exciting phenomena related to them. We do not attempt to cover all existing models …

Large deviation principle for geometric and topological functionals and associated point processes

C Hirsch, T Owada - The Annals of Applied Probability, 2023 - projecteuclid.org
We prove a large deviation principle for the point process associated to k-element
connected components in R d with respect to the connectivity radii rn→∞. The random …

This paper develops the large deviations theory for the point process associated with the
Euclidean volume of $ k $-nearest neighbor balls centered around the points of a …

Limit laws for large th-nearest neighbor balls

N Chenavier, N Henze, M Otto - Journal of Applied Probability, 2022 - cambridge.org
Let be a sequence of independent random points in with common Lebesgue density f.
Under some conditions on f, we obtain a Poisson limit theorem, as, for the number of large …

Large nearest neighbour balls in hyperbolic stochastic geometry

M Otto, C Thäle - Extremes, 2023 - Springer
Consider a stationary Poisson process in ad-dimensional hyperbolic space. For R> 0 define
the point process ξ R (k) of exceedance heights over a suitable threshold of the hyperbolic …

Homological connectivity in random Čech complexes

O Bobrowski - Probability Theory and Related Fields, 2022 - Springer
We study the homology of random Čech complexes generated by a homogeneous Poisson
process. We focus on 'homological connectivity'—the stage where the random complex is …

Disagreement coupling of Gibbs processes with an application to Poisson approximation

G Last, M Otto - The Annals of Applied Probability, 2023 - projecteuclid.org
We discuss a thinning and an embedding procedure to construct finite Gibbs processes with
a given Papangelou intensity. Extending the approach of Hofer-Temmel (Electron. J …

Large deviations for hyperbolic -nearest neighbor balls

We prove a large deviation principle for the point process of large Poisson $ k $-nearest
neighbor balls in hyperbolic space. More precisely, we consider a stationary Poisson point …

Compound Poisson process approximation under -mixing and stabilization

N Chenavier, M Otto - arxiv preprint arxiv:2310.15009, 2023 - arxiv.org
We establish Poisson and compound Poisson approximations for stabilizing statistics of
$\beta $-mixing point processes and give explicit rates of convergence. Our findings are …
