Difference between families of weakly and strongly maximal integral lattice-free polytopes
A $d$-dimensional closed convex set $K$ in $\mathbb{R}^d$ is said to be lattice-free if the interior of $K$ is disjoint with $\mathbb{Z}^d$. We consider the following two families of lattice-freeExpand
Classification of empty lattice 4-simplices of width larger than two
• Mathematics
• 2017
A lattice $d$-simplex is the convex hull of $d+1$ affinely independent integer points in ${\mathbb R}^d$. It is called empty if it contains no lattice point apart of its $d+1$ vertices. TheExpand
Recognition of Digital Polyhedra with a Fixed Number of Faces Is Decidable in Dimension 3
The problem to determine whether there exists a (rational) polyhedron with at most n faces and verifying $$P \cap \mathbb {Z}^d= S$$ is decidable is considered. Expand
Complexity of linear relaxations in integer programming
• Mathematics
• 2020
For a set $X$ of integer points in a polyhedron, the smallest number of facets of any polyhedron whose set of integer points coincides with $X$ is called the relaxation complexity $\mathrm{rc}(X)$.Expand

It is shown that S_{d,k} is a volume maximizer in the family of simplices S \in S^d(k) that have a facet with one lattice point in its relative interior that is unique up to unimodular transformations. Expand
Enumerating lattice 3-polytopes
• Computer Science, Mathematics
• Electron. Notes Discret. Math.
• 2016
This work presents a full enumeration of lattice 3-polytopes via their size and width, finding that most of them contain two proper subpolytopes of width larger than one, and thus can be obtained from the list of size n − 1 using computer algorithms. Expand
The complete classification of empty lattice $4$-simplices
An empty simplex is a lattice simplex with only its vertices as lattice points. Their classification in dimension three was completed by G. White in 1964. In dimension four, the same task was startedExpand
Classification of triples of lattice polytopes with a given mixed volume

We present an algorithm for the classification of triples of lattice polytopes with a given mixed volume $m$ in dimension 3. It is known that the classification can be reduced to the enumeration ofExpand

Abstract Combining an upper bound on the volume of empty lattice 4-simplices of large width with a computer enumeration we prove the following conjecture of Haase and Ziegler (2000): Except for 179Expand
The complete classification of empty lattice 4-simplices

All empty 4-simplices of width at least three are classified, including those of width two, which reveals two two-parameter families that project to the second dilation of a unimodular triangle and many more that do not. Expand

A lattice $3$-polytope is a polytope $P$ with integer vertices. We call size of $P$ the number of lattice points it contains, and width of $P$ the minimum, over all integer linear functionals $f$, ofExpand

An Introduction to Empty Lattice Simplices
It is already NP-complete to decide whether the width of a very special class of integer simplices is 1, and it is provided for every n ≥ 3 a simple example of n-dimensional emptyinteger simplices of width n - 2, improving on earlier bounds. Expand
