Low degree minimal generators of phylogenetic semigroups
Kaie Kubjas
The phylogenetic semigroup on a graph generalizes the Jukes-Cantor binary model on a tree. Minimal generating sets of phylogenetic semigroups have been described for trivalent tree…

On the graph labellings arising from phylogenetics
Weronika Buczyńska, Jarosław Buczyński, Kaie Kubjas +1
We study semigroups of labellings associated to a graph. These generalize the Jukes-Cantor model and phylogenetic toric varieties defined by Buczyńska. Our main theorem bounds the…
