Title: | Orders and actions of branched coverings of hyperbolic links | Authors: | Salgueiro, António | Keywords: | Group actions; Strongly branched coverings; Orbifolds; Hyperbolic volume | Issue Date: | 2006 | Publisher: | Centro de Matemática da Universidade de Coimbra | Citation: | Pré-Publicações DMUC. 06-58 (2006) | Abstract: | Let M, M′ be compact oriented 3-manifolds and L′ a link in M′ whose exterior has positive Gromov norm. We prove that the topological types of M and (M′,L′) determine the degree of a strongly cyclic covering p : M → M′, branched over L′. Moreover, if M′ is an homology sphere then these topological types determine also the covering up to conjugacy. | URI: | https://hdl.handle.net/10316/11319 | Rights: | openAccess |
