Counting symmetric unimodular triangulations
Kamillo Ferry, Michael Joswig, Jörg Rambau
The objects of study are triangulations of the dilated standard triangle in the plane. Motivated by work on T-curves (Geiselmann et al., 2026), the focus lies on unimodular triangu…
Polyhedral Aspects of Maxoids
Tobias Boege, Kamillo Ferry, Benjamin Hollering +1
The conditional independence (CI) relation of a distribution in a max-linear Bayesian network depends on its weight matrix through the -separation criterion. These CI~model…
Tropical combinatorics of max-linear Bayesian networks
Carlos Améndola, Kamillo Ferry
A polytrope is a tropical polyhedron that is also classically convex. We study the tropical combinatorial types of polytropes associated to weighted directed acyclic graphs (DAGs).…
Good Triangulations of Cosmological Polytopes
Aenne Benjes, Kamillo Ferry, Benjamin Schröter
Cosmological polytopes of graphs are a geometric tool in physics to study wavefunctions for cosmological models whose Feynman diagram is given by the graph. After their recent intr…
