Comparing and simplifying distinct-cluster phylogenetic networks
Stephen J. Willson
Phylogenetic networks are rooted acyclic directed graphs in which the leaves are identified with members of a set X of species. The cluster of a vertex is the set of leaves that ar…
Restricted trees: simplifying networks with bottlenecks
Stephen J. Willson
Suppose N is a phylogenetic network indicating a complicated relationship among individuals and taxa. Often of interest is a much simpler network, for example, a species tree T, th…
CSD Homomorphisms Between Phylogenetic Networks
Stephen J. Willson
Since Darwin, species trees have been used as a simplified description of the relationships which summarize the complicated network of reality. Recent evidence of hybridization…
Regular networks are determined by their trees
Stephen J. Willson
A rooted acyclic digraph N with labelled leaves displays a tree T when there exists a way to select a unique parent of each hybrid vertex resulting in the tree T. Let Tr(N) denote…
