Framingtopes

Sergio Alejandro Fernandez de soto Guerrero, Cesar Ceballos, Matias von Bell

Framing lattices arise from the dual graphs of framed (or DKK) triangulations of flow polytopes and provide a common framework encompassing classical lattices such as the Boolean,…

A subdivision algebra for a product of two simplices via flow polytopes

Matias von Bell

For a lattice path $ν$ from the origin to a point $(a, b)$ using steps $E = (1, 0)$ and $N = (0, 1)$ , we construct an associated flow polytope $F_{G^_{B} (ν)}$ arising from an…

Triangulations of Flow Polytopes, Ample Framings, and Gentle Algebras

Matias von Bell, Benjamin Braun, Kaitlin Bruegge +4

The cone of nonnegative flows for a directed acyclic graph (DAG) is known to admit regular unimodular triangulations induced by framings of the DAG. These triangulations restrict t…
