Graded Cohen-Macaulay domains and lattice polytopes with short -vector

Lukas Katthän, Kohji Yanagawa

Let P be a lattice polytope with -vector . In this note we show that if , then is IDP. More generally, we show the corresponding state…

A unified framework of SAGE and SONC polynomials and its duality theory

Lukas Katthän, Helen Naumann, Thorsten Theobald

We introduce and study a cone which consists of a class of generalized polynomial functions and which provides a common framework for recent non-negativity certificates of polynomi…

Smooth centrally symmetric polytopes in dimension 3 are IDP

Matthias Beck, Christian Haase, Akihiro Higashitani +4

In 1997 Oda conjectured that every smooth lattice polytope has the integer decomposition property. We prove Oda's conjecture for centrally symmetric -dimensional polytopes, by s…

When is a polynomial ideal binomial after an ambient automorphism?

Lukas Katthän, Mateusz Michałek, Ezra Miller

Can an ideal I in a polynomial ring k[x] over a field be moved by a change of coordinates into a position where it is generated by binomials with c in k, or by unital…

Finding binomials in polynomial ideals

Anders Jensen, Thomas Kahle, Lukas Katthän

We describe an algorithm which finds binomials in a given ideal and in particular decides whether binomials exist in at all. Binomials in po…

Algebraic properties of ideals of poset homomorphisms

Martina Juhnke-Kubitzke, Lukas Katthän, Sara Saeedi Madani

Given finite posets and , we consider a specific ideal , whose minimal monomial generators correspond to order-preserving maps . We study algebraic…
