Poisson hulls
@inproceedings{Last2022PoissonH, title={Poisson hulls}, author={Gunter Last and Ilya Molchanov}, year={2022} }
: We introduce a hull operator on Poisson point processes, the easiest example being the convex hull of the support of a point process in Euclidean space. Assuming that the intensity measure of the process is known on the set generated by the hull operator, we discuss estimation of the expected linear statistics built on the Poisson process. In special cases, our general scheme yields an estimator of the volume of a convex body or an estimator of an integral of a H¨older function. We show that…

Central limit theorems for $U$-statistics of Poisson point processes are shown, with explicit bounds for the Wasserstein distance to a Gaussian random variable and the length of a random geometric graph are investigated.

A natural model for the approximation of a convex body $K$ in $\mathbb{R}^d$ by random polytopes is obtained as follows. Take a stationary Poisson hyperplane process in the space, and consider the…
Methods for Estimation of Convex Sets

This work focuses on the estimation of convex sets under the Nykodim and the Hausdorff metrics, which require different techniques and, quite surprisingly, lead to very different results, in particular in density support estimation.
Invariance of Poisson measures under random transformations

We prove that Poisson measures are invariant under (random) intensity preserving transformations whose finite difference gradient satisfies a cyclic vanishing condition. The proof relies on moment…
