Flux moyen d'un courant électrique dans un réseau aléatoire stationnaire de résistances
Résumé
In a preceding note the pointwise ergodic theorem for cocycle of degree 2 of a Z3 action has been proved under the hypothesis of Lp integrability for one p> 2. We prove here that the current through surfaces in a random electrical network defines a cocycle of degree 2, to which this theorem can be applied.
