Laplacian Simplices Associated to Digraphs

Gabriele Balletti, Takayuki Hibi, Marie Meyer +1

We associate to a finite digraph $D$ a lattice polytope $P_{D}$ whose vertices are the rows of the Laplacian matrix of $D$ . This generalizes a construction introduced by Braun and th…

Laplacian Simplices

Benjamin Braun, Marie Meyer

This paper initiates the study of the "Laplacian simplex" $T_{G}$ obtained from a finite graph $G$ by taking the convex hull of the columns of the Laplacian matrix for $G$ . Basic pro…
