Root bounds of vertical systems using tropical geometry
Elisenda Feliu, Paul Alexander Helminck, Oskar Henriksson +3
Sparse polynomial systems with vertical coefficient dependencies arise naturally when describing the critical points of optimization problems and, when augmented with linear forms,…

Chow classes of matroids and standard Young tableaux
Jon Pål Hamre, Benjamin Schröter, Lorenzo Vecchi +1
We study the Chow classes of arbitrary matroids in the Grassmannian. We develop a new combinatorial approach for computing them, by first focusing on snake matroids and then extend…

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…
