Exact--Relation Graphs
Yangjing Long, Peter F. Stadler
Pairwise compatibility graphs (PCGs) with non-negative integer edge weights recently have been used to describe rare evolutionary events and scenarios with horizontal gene transfer…
Unrooted non-binary tree-based phylogenetic networks
Mareike Fischer, Michelle Galla, Lina Herbst +2
Phylogenetic networks are a generalization of phylogenetic trees allowing for the representation of non-treelike evolutionary events such as hybridization. Typically, such networks…
Classes of treebased networks
Mareike Fischer, Michelle Galla, Lina Herbst +2
Recently, so-called treebased phylogenetic networks have gained considerable interest in the literature, where a treebased network is a network that can be constructed from a phylo…
Phylogenetic trees and homomorphisms
Yangjing Long
In Chapter 1 we fully characterise pairs of finite graphs which form a gap in the full homomorphism order. This leads to a simple proof of the existence of generalised duality pair…
A Short Note on Undirected Fitch Graphs
Manuela Geiß, Marc Hellmuth, Yangjing Long +1
The symmetric version of Fitch's xenology relation coincides with class of complete multipartite graph and thus cannot convey any non-trivial phylogenetic information.
Word-representability of split graphs
Sergey Kitaev, Yangjing Long, Jun Ma +1
Letters and alternate in a word if after deleting in all letters but the copies of and we either obtain a word (of even or odd length) or a wor…
