Dans cet article, je considère un revêtement riemannien. Je démontre que l’existence de la fonction de Green sur est équivalente au fait que , le groupe de revêtement, est “transient" (à condition que soit compacte).
In this paper I consider a covering of a Riemannian manifold . I prove that Green’s function exists on if any and only if the symmetric translation invariant random walks on the covering group are transient (under the assumption that is compact).
