Recurrence versus transience for weight-dependent random connection models

P Gracar, M Heydenreich, C Mönch… - Electronic Journal of …, 2022 - projecteuclid.org
We investigate random graphs on the points of a Poisson process in d-dimensional space,
which combine scale-free degree distributions and long-range effects. Every Poisson point …

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 …

On the uniqueness of the infinite cluster and the cluster density in the Poisson driven random connection model

M Chebunin, G Last - arxiv preprint arxiv:2403.17762, 2024 - arxiv.org
We consider a random connection model (RCM) on a general space driven by a Poisson
process whose intensity measure is scaled by a parameter $ t\ge 0$. We say that the infinite …

Four universal growth regimes in degree-dependent first passage percolation on spatial random graphs I

J Komjáthy, J Lapinskas, J Lengler… - arxiv preprint arxiv …, 2023 - arxiv.org
One-dependent first passage percolation is a spreading process on a graph where the
transmission time through each edge depends on the direct surroundings of the edge. In …

Chemical distance in geometric random graphs with long edges and scale-free degree distribution

P Gracar, A Grauer, P Mörters - Communications in Mathematical Physics, 2022 - Springer
We study geometric random graphs defined on the points of a Poisson process in d-
dimensional space, which additionally carry independent random marks. Edges are …

Cluster-size decay in supercritical kernel-based spatial random graphs

J Jorritsma, J Komjáthy, D Mitsche - arxiv preprint arxiv:2303.00724, 2023 - arxiv.org
We consider a large class of spatially-embedded random graphs that includes among others
long-range percolation, continuum scale-free percolation and the age-dependent random …

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 …

Critical exponents for marked random connection models

A Caicedo, M Dickson - Electronic Journal of Probability, 2024 - projecteuclid.org
Here we prove critical exponents for Random Connections Models (RCMs) with random
marks. The vertices are given by a marked Poisson point process on R d and an edge exists …

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 …
