The geometry of geometries: matroid theory, old and new

Federico Ardila

The theory of matroids or combinatorial geometries originated in linear algebra and graph theory, and has deep connections with many other areas, including field theory, matching t…

Lagrangian combinatorics of matroids

Federico Ardila, Graham Denham, June Huh

The Lagrangian geometry of matroids was introduced in [ADH20] through the construction of the conormal fan of a matroid M. We used the conormal fan to give a Lagrangian-geometric i…

Valuations and the Hopf Monoid of Generalized Permutahedra

Federico Ardila, Mario Sanchez

The goal of this paper is to show that valuation theory and Hopf theory are compatible on the class of generalized permutahedra. We prove that the Hopf structure on…

The bipermutahedron

Federico Ardila

The harmonic polytope and the bipermutahedron are two related polytopes which arose in Ardila, Denham, and Huh's work on the Lagrangian geometry of matroids. We study the bipermuta…

The harmonic polytope

Federico Ardila, Laura Escobar

We study the harmonic polytope, which arose in Ardila, Denham, and Huh's work on the Lagrangian geometry of matroids. We describe its combinatorial structure, showing that it is a…

The Arithmetic of Coxeter Permutahedra

Federico Ardila, Matthias Beck, Jodi McWhirter

Ehrhart theory measures a polytope P discretely by counting the lattice points inside its dilates P, 2P, 3P, .... We compute the Ehrhart quasipolynomials of the standard Coxeter pe…
