  • Comparison of Tree-Child Phylogenetic Networks 

    Cardona, Gabriel; Rosselló, Francesc; Valiente Feruglio, Gabriel Alejandro (2009-11-03)
    Article
    Open Access
    Phylogenetic networks are a generalization of phylogenetic trees that allow for the representation of nontreelike evolutionary events, like recombination, hybridization, or lateral gene transfer. While much progress has ...
  • On Nakhleh's metric for reduced phylogenetic networks 

    Cardona, Gabriel; Llabrés, Mercè; Rosselló, Francesc; Valiente Feruglio, Gabriel Alejandro (2009-11)
    Article
    Open Access
    We prove that Nakhleh’s metric for reduced phylogenetic networks is also a metric on the classes of tree-child phylogenetic networks, semibinary tree-sibling time consistent phylogenetic networks, and multilabeled ...
  • On the ancestral compatibility of two phylogenetic trees with nested taxa 

    Llabrés Segura, Mercè; Rocha, Jairo; Rosselló, Francesc; Valiente Feruglio, Gabriel Alejandro (2005-05)
    External research report
    Open Access
    Compatibility of phylogenetic trees is the most important concept underlying widely-used methods for assessing the agreement of different phylogenetic trees with overlapping taxa and combining them into common supertrees ...
  • Rewriting in categories of spans 

    Monserrat, Miquel; Rosselló, Francesc; Torrens, Joan; Valiente Feruglio, Gabriel Alejandro (1996-03)
    External research report
    Open Access
    Single-pushout transformation in a category of spans, in some sense a generalization of the usual notion of partial morphism, is studied in this paper. Contrary to the usual notion of partial morphism, spans are single ...
