Voronoi-Based Vacuum Leakage Detection in Composite Manufacturing
Christoph Brauer, Arne Hindersmann, Timo de Wolff
In this article, we investigate vacuum leakage detection problems in composite manufacturing. Our approach uses Voronoi diagrams, a well-known structure in discrete geometry. The V…
Nonnegativity of signomials with Newton simplex over -convex sets
Gennadiy Averkov, Jonas Ellwanger, Thorsten Theobald +1
We study a class of signomials whose positive support is the set of vertices of a simplex and which may have several negative support points in the simplex. Various groups of autho…
A Generalized Muirhead Inequality and Symmetric Sums of Nonnegative Circuits
Janin Heuer, Ngoc Mai Tran, Timo de Wolff
Circuit polynomials are a certificate of nonnegativity for real polynomials, which can be derived via a generalization of the classical inequality of arithmetic and geometric means…
Computing the Real Isolated Points of an Algebraic Hypersurface
Huu Phuoc Le, Mohab Safey El Din, Timo de Wolff
Let be the field of real numbers. We consider the problem of computing the real isolated points of a real algebraic set in given as the vanishing set of…
Initial Steps in the Classification of Maximal Mediated Sets
Jacob Hartzer, Olivia Röhrig, Timo de Wolff +1
Maximal mediated sets (MMS), introduced by Reznick, are distinguished subsets of lattice points in integral polytopes with even vertices. MMS of Newton polytopes of AGI-forms and n…
Computing Elimination Ideals and Discriminants of Likelihood Equations
Xiaoxian Tang, Timo De Wolff, Rukai Zhao
We develop a probabilistic algorithm for computing elimination ideals of likelihood equations, which is for larger models by far more efficient than directly computing Groebner bas…
Optimization over the Boolean Hypercube via Sums of Nonnegative Circuit Polynomials
Mareike Dressler, Adam Kurpisz, Timo de Wolff
Various key problems from theoretical computer science can be expressed as polynomial optimization problems over the boolean hypercube. One particularly successful way to prove com…
Nondegenerate multistationarity in small reaction networks
Anne Shiu, Timo de Wolff
Much attention has been focused in recent years on the following algebraic problem arising from applications: which chemical reaction networks, when taken with mass-action kinetics…
Low Dimensional Test Sets for Nonnegativity of Even Symmetric Forms
Sadik Iliman, Timo de Wolff
An important theorem by Timofte states that nonnegativity of real -variate symmetric polynomials of degree can be decided at test sets given by all points with at most $\lfl…
Polytopes with Special Simplices
Timo de Wolff
For a polytope P a simplex S with vertex set V(S) is called a special simplex if every facet of P contains all but exactly one vertex of S. For such polytopes P with face complex F…
