“…In this context, the holonomy of leaves is closely related to the uniformizations of leaves and their Poincaré metric. This subject has received a lot of attention in the recent years (see, for example, the works by Candel [2], Candel-Gómez Mont [6], Dinh-Nguyen-Sibony [12,13,14], Fornaess-Sibony [16,17,18], Neto [28] etc). We also hope that the results of this Memoir may find applications in the dynamics of moduli spaces and in the geometric dynamics of laminations and foliations.…”
