摘要
In this paper, we obtain several results on the commensurability of two Kleinian groups and their limit sets. We prove that two finitely generated subgroups G(1) and G(2) of an infinite co-volume Kleinian group G subset of Isom(H(3)) having Lambda(G(1)) = Lambda(G(2)) are commensurable. In particular, we prove that any finitely generated subgroup H of a Kleinian group G subset of Isom(H(3)) with Lambda(H) = Lambda(G) is of finite index if and only if H is not a virtually fibered subgroup.
