  1. Branched coverings of links whose geometric graph contains one cycle. Let M, M' be compact, connected, oriented 3-manifolds and L' a link in M' with irreducible exterior E'. We prove that if the geometric graph of E' has a single cycle then there exists at most one prime number d for which M is a cyclic covering of M', of order d, branched over L'.. 2009.

  2. Orders of branched covering of links. Let M, M' be compact oriented 3-manifolds and L' a link in M'. We prove that, under certain conditions, the topological types of M and (M',L') determine the degree of a cyclic covering p : M ¿ M', branched over L'.. 2006.

  3. Orders and actions of branched coverings of hyperbolic links. 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.. 2006. Salgueiro, António. http://hdl.handle.net/10316/11319.
