Large deviations of the giant in supercritical kernel-based spatial random graphs

J Jorritsma, J Komjáthy, D Mitsche - arxiv preprint arxiv:2404.02984, 2024 - arxiv.org
We study cluster sizes in supercritical $ d $-dimensional inhomogeneous percolation
models with long-range edges--such as long-range percolation--and/or heavy-tailed degree …

Finiteness of the percolation threshold for inhomogeneous long-range models in one dimension

P Gracar, L Lüchtrath, C Mönch - arxiv preprint arxiv:2203.11966, 2022 - arxiv.org
We consider inhomogeneous spatial random graphs on the real line. Each vertex carries an
iid weight and edges are drawn such that short edges and edges to vertices with large …

Existence of subcritical percolation phases for generalised weight-dependent random connection models

B Jahnel, L Lüchtrath - arxiv preprint arxiv:2302.05396, 2023 - arxiv.org
We derive a sufficient condition for the existence of a subcritical percolation phase for a wide
range of continuum percolation models where each vertex is embedded into Euclidean …

Continuity of the critical value for long-range percolation

J Bäumler - arxiv preprint arxiv:2312.04099, 2023 - arxiv.org
We show that for long-range percolation with polynomially decaying connection probabilities
in dimension $ d\geq 2$, the critical value depends continuously on the precise …

Recurrence and transience of symmetric random walks with long-range jumps

J Bäumler - Electronic Journal of Probability, 2023 - projecteuclid.org
Abstract Let X 1, X 2,… be iid random variables with values in Z d satisfying PX 1= x= PX
1=− x= Θ‖ x‖− s for some s> d. We show that the random walk defined by S n=∑ k= 1 n X …

Cluster sizes in subcritical soft Boolean models

B Jahnel, L Lüchtrath, M Ortgiese - arxiv preprint arxiv:2404.13730, 2024 - arxiv.org
We consider the soft Boolean model, a model that interpolates between the Boolean model
and long-range percolation, where vertices are given via a stationary Poisson point process …

Subcritical annulus crossing in spatial random graphs

E Jacob, B Jahnel, L Lüchtrath - arxiv preprint arxiv:2411.10333, 2024 - arxiv.org
We consider general continuum percolation models obeying sparseness, translation
invariance, and spatial decorrelation. In particular, this includes models constructed on …

All spatial random graphs with weak long-range effects have chemical distance comparable to Euclidean distance

L Lüchtrath - arxiv preprint arxiv:2412.12796, 2024 - arxiv.org
This note provides a sufficient condition for linear lower bounds on chemical distances
(compared to the Euclidean distance) in general spatial random graphs. The condition is …

Truncation of long-range percolation with non-summable interactions in dimensions

J Bäumler - arxiv preprint arxiv:2410.00303, 2024 - arxiv.org
Consider independent long-range percolation on $\mathbb {Z}^ d $ for $ d\geq 3$.
Assuming that the expected degree of the origin is infinite, we show that there exists an …

Inhomogeneous long-range percolation in the strong decay regime: recurrence in one dimension

C Mönch - arxiv preprint arxiv:2408.06918, 2024 - arxiv.org
We provide a sufficient criterion for the recurrence of spatial random graphs on the real line
based on the scarceness of long-edges. In particular, this complements earlier recurrence …
