Quasihomomorphisms from the integers into Hamming metrics

Jan Draisma, Rob H. Eggermont, Tim Seynnaeve +2

A function $f : Z \to Q^{n}$ is a $c$ -quasihomomorphism if the Hamming distance between $f (x + y)$ and $f (x) + f (y)$ is at most $c$ for all $x, y \in Z$ . We show…

Phylogenetic complexity of the Kimura 3-parameter model

Mateusz Michałek, Emanuele Ventura

In algebraic statistics, the Kimura 3-parameter model is one of the most interesting and classical phylogenetic models. We prove that the ideals associated to this model are genera…

Finite phylogenetic complexity and combinatorics of tables

Mateusz Michałek, Emanuele Ventura

We prove that the phylogenetic complexity -- an invariant introduced by Sturmfels and Sullivant -- of any finite abelian group is finite.

The poset of proper divisibility

Davide Bolognini, Antonio Macchia, Emanuele Ventura +1

We study the partially ordered set $P (a_{1}, \dots, a_{n})$ of all multidegrees $(b_{1}, \dots, b_{n})$ of monomials $x_{1}^{b_{1}} \dots x_{n}^{b_{n}}$ which properly divide $x_1^{a_1}\cdots x_n^{a…
