On Agreement Subtrees in Multiple Phylogenetic Trees
Bryan Currie, Éva Czabarka, Mareike Fischer +3
Snir and Yuster [Discrete Appl. Math. 347 (2026) 160--171] asked for the least number such that unrooted binary phylogenetic trees on the same leaves always share…
Curious crossing-critical edges
Éva Czabarka, Alec Helm
Motivated by Kuratowski's theorem, a Kuratowski subgraph of a graph is a subgraph that is a subdivided or a subdivided . An edge is crossing-critical if the crossing…
Coconvex characters on collections of phylogenetic trees
Eva Czabarka, Steven Kelk, Vincent Moulton +1
In phylogenetics, a key problem is to construct evolutionary trees from collections of characters where, for a set X of species, a character is simply a function from X onto a set…
Reconstruction of caterpillar tanglegrams
Ann Clifton, Eva Czabarka, Kevin Liu +4
A tanglegram consists of two rooted binary trees with the same number of leaves and a perfect matching between the leaves of the trees. Given a size- tanglegram, i.e., a tangleg…
Decks of rooted binary trees
Ann Clifton, Eva Czabarka, Audace Dossou-Olory +5
We consider extremal problems related to decks and multidecks of rooted binary trees (a.k.a. rooted phylogenetic tree shapes). Here, the deck (resp. multideck) of a tree refers…
Universal rooted phylogenetic tree shapes and universal tanglegrams
Ann Clifton, Eva Czabarka, Kevin Liu +4
We provide an lower bound and an upper bound for the smallest size of rooted binary trees (a.k.a. phylogenetic tree shapes), which are universal for rooted b…
