Hypergraphic zonotopes and acyclohedra

open access: yesBulletin of the London Mathematical Society
Abstract We introduce a higher uniformity analogue of graphic zonotopes and permutohedra. Specifically, given a ‐uniform hypergraph , we define its hypergraphic zonotope , and when is the complete ‐uniform hypergraph , we call its hypergraphic zonotope the

Zonoids, Linear Dependence, and Size-Biased Distributions on the Simplex. [PDF]

open access: yes
The zonoid of a d-dimensional random vector is used as a tool for measuring linear dependence among its components. A preorder of linear dependence is defined through inclusion of the zonoids.

Hyperplanes Based Zonotopic Contractor

open access: yes
This article introduces a novel method for constructing a "zonotopic contractor" based on hyperplane properties. While zonotopes, a special class of polytopes, offer computational advantages due to their symmetric matrix representation, they are not closed under intersection, often necessitating over-approximations that lead to conservatism in ...

Plabic graphs and zonotopal tilings

open access: yes, 2016
We say that two sets $S,T\subset\{1,2,\dots,n\}$ are chord separated if there does not exist a cyclically ordered quadruple $a,b,c,d$ of integers satisfying $a,c\in S-T$ and $b,d\in T-S$. This is a weaker version of Leclerc and Zelevinsky's weak separation.
