Combinatorics of higher-dimensional tropical covers

Alejandro Vargas

We develop a combinatorial framework to study certain polyhedral maps which are higher-dimensional analogues of tropical covers between metric graphs. Under a mild combinatorial as…

Buildings, valuated matroids, and tropical linear spaces

Luca Battistella, Kevin Kuehn, Arne Kuhrs +2

Affine Bruhat--Tits buildings are geometric spaces extracting the combinatorics of algebraic groups. The building of $PGL$ parametrizes flags of subspaces/lattices in or,…

One-quasihomomorphisms from the integers into symmetric matrices

Tim Seynnaeve, Nafie Tairi, Alejandro Vargas

A function $f$ from $Z$ to the symmetric matrices over an arbitrary field $K$ of characteristic $0$ is a $1$ -quasihomomorphism if the matrix $f (x + y) - f (x) - f (y)$ has ran…
