The space of equidistant phylogenetic cactuses
Katharina T. Huber, Vincent Moulton, Megan Owen +2
We introduce and investigate the space of \emph{equidistant} -\emph{cactuses}. These are rooted, arc weighted, phylogenetic networks with leaf set , where is a finite set…
Maximum Covering Subtrees for Phylogenetic Networks
Nathan Davidov, Amanda Hernandez, Justin Jian +9
Tree-based phylogenetic networks, which may be roughly defined as leaf-labeled networks built by adding arcs only between the original tree edges, have elegant properties for model…
Geometric comparison of phylogenetic trees with different leaf sets
Gillian Grindstaff, Megan Owen
The metric space of phylogenetic trees defined by Billera, Holmes, and Vogtmann, which we refer to as BHV space, provides a natural geometric setting for describing collections of…
Mean and Variance of Phylogenetic Trees
Daniel G. Brown, Megan Owen
We describe the use of the Frechet mean and variance in the Billera-Holmes-Vogtmann (BHV) treespace to summarize and explore the diversity of a set of phylogenetic trees. We show t…
On Determining if Tree-based Networks Contain Fixed Trees
Maria Anaya, Olga Anipchenko-Ulaj, Aisha Ashfaq +9
We address an open question of Francis and Steel about phylogenetic networks and trees. They give a polynomial time algorithm to decide if a phylogenetic network, N, is tree-based…
A Fast Algorithm for Computing Geodesic Distances in Tree Space
Megan Owen, J. Scott Provan
Comparing and computing distances between phylogenetic trees are important biological problems, especially for models where edge lengths play an important role. The geodesic distan…
