Abstract

We study the trace of the incipient infinite oriented branching random walk in Zd×Z+ when the dimension is d=6. Under suitable moment assumptions, we show that the electrical resistance between the root and level n is O(nlogξn) for a ξ>0 that does not depend on details of the model.

Nous étudions la trace de la marche aléatoire branchante critique conditionnée à être infinie sur Zd×Z+, en dimension d=6. Sous des hypothèses appropriées sur les moments de la marche et de la loi de reproduction, nous démontrons que la résistance électrique entre la racine et le niveau n est d’ordre O(nlogξn) pour un certain ξ>0 qui ne dépend pas des détails du modèle.
