Elephant polynomials

Hélène Guérin, Lucile Laulin, Kilian Raschel

In this note, we study a family of polynomials that appear naturally when analysing the characteristic functions of the one-dimensional elephant random walk. These polynomials depe…

Logarithmic terms in discrete heat kernel expansions in the quadrant

Andrew Elvey-Price, Andreas Nessmann, Kilian Raschel

In the context of lattice walk enumeration in cones, we consider the number of walks in the quarter plane with fixed starting and ending points, prescribed step-set and given lengt…

Random Walks in the High-Dimensional Limit II: The Crinkled Subordinator

Zakhar Kabluchko, Alexander Marynych, Kilian Raschel

A crinkled subordinator is an -valued random process which can be thought of as a version of the usual one-dimensional subordinator with each out of countably many jumps be…

Multivariate multiplicative functions of uniform random vectors in large integer domains

Zakhar Kabluchko, Oleksandr Marynych, Kilian Raschel

For a wide class of sequences of integer domains , , we prove distributional limit theorems for , w…

Harmonic functions for singular quadrant walks

Viet Hung Hoang, Kilian Raschel, Pierre Tarrago

We consider discrete (time and space) random walks confined to the quarter plane, with jumps only in directions with and small negative jumps, i.e., $i,j \geq…

A dual skew symmetry for transient reflected Brownian motion in an orthant

Sandro Franceschi, Kilian Raschel

We introduce a transient reflected Brownian motion in a multidimensional orthant, which is either absorbed at the apex of the cone or escapes to infinity. We address the question o…
