[PDF][PDF] Martin boundary of random walks in convex cones

K Raschel, P Tarrago - arXiv preprint arXiv:1803.09253, 2018 - hal.science
We determine the asymptotic behavior of the Green function for zerodrift random walks
confined to multidimensional convex cones. As a consequence, we prove that (up to a …

In this paper, we obtain the exact asymptotic behavior of Green functions of homogeneous
random walks in Z d killed at the first exit from and open cone of R d. Our approach …

Martin boundary of a killed non-centered random walk in a general cone

I Ignatiouk-Robert - arXiv preprint arXiv:2006.15870, 2020 - arxiv.org
We investigate Martin boundary for a non-centered random walk on ${\mathbb Z}^ d $ killed
up on the time $\tau_\vartheta $ of the first exit from a convex cone with a vertex at $0 $. The …

Waiting Times for Ties in Random Competitions

I Matic - arXiv preprint arXiv:2105.01310, 2021 - arxiv.org
Multiple teams participate in a random competition. In each round the winner receives one
point. We study the times until ties occur among teams. We construct martingales and …

[PDF][PDF] Essays on random walks in cones

J Duraj - 2020 - edoc.ub.uni-muenchen.de
Consider a random walk {S (n), n≥ 1} on Rd, d≥ 2, where S (n)=∑ ni= 1 X (i) with {X (n),
n≥ 1} is a family of iid random variables in Rd. Let K⊂ Rd be an open cone and τx= inf {n≥ …

Multidimensional Random Walks Conditioned to Stay Ordered via Generalized Ladder Height Functions

Random walks conditioned to stay positive are a prominent topic in fluctuation theory. One
way to construct them is as a random walk conditioned to stay positive up to time n, and let n …
