## TL;DR

This paper proves that polynomial-size vectors are sufficient for unimodular triangulations of simplicial cones, significantly improving previous exponential bounds and establishing a polynomial bound in the cone's multiplicity.

## Contribution

The authors demonstrate the existence of a polynomial bound in the multiplicity for unimodular triangulations, advancing understanding of the geometric structure of simplicial cones.

## Key findings

- Established a polynomial bound in multiplicity for unimodular triangulations.
- Improved previous exponential bounds to polynomial bounds.
- Provided a bound of the form μ^{f(d)} with f(d) in O(d).

## Abstract

In a recent paper, Bruns and von Thaden established a bound for the length of vectors involved in a unimodular triangulation of simplicial cones. The bound is exponential in the square of the logarithm of the multiplicity, and improves previous bounds significantly. The authors mentioned that the next goal would be a bound that is polynomial in the multiplicity but not knowing if such a bound exists. In this paper we will prove that such a bound, which is polynomial in the multiplicity $\mu$, indeed exists. In detail, the bound is of the type $\mu^{f(d)}$ with $f(d) \in \mathcal{O}(d)$.
