A combinatorial approach to a model of constrained random walkers

Thibault Espinasse, Nadine Guillotin-Plantard, Philippe Nadeau

In [1], the authors consider a random walk $(Z_{n,1},\dots ,Z_{n,K+1})\in {\mathbb{Z}}^{K+1}$ with the constraint that each coordinate of the walk is at distance one from the followi…
