Deformation cones of graph associahedra and nestohedra

  title={Deformation cones of graph associahedra and nestohedra},
  author={Arnau Padrol and Vincent Pilaud and Germain Poullot},
We give the facet description of the deformation cones of graph associahedra and nestohedra, generalizing the classical parametrization of the family of deformed permutahedra by the cone of submodular functions. When the underlying building set is made of intervals, this yields in particular to the construction of kinematic nestohedra generalizing the kinematic associahedra that recently appeared in the theory of scattering amplitudes.

Acyclic reorientation lattices and their lattice quotients
We prove that the acyclic reorientation poset of a directed acyclic graph D is a lattice if and only if the transitive reduction of any induced subgraph of D is a forest. We then show that theExpand
Deformed graphical zonotopes
We study deformations of graphical zonotopes. Deformations of the classical permutahedron (which is the graphical zonotope of the complete graph) have been intensively studied in recent years underExpand


Coxeter Complexes and Graph-Associahedra
Abstract Given a graph Γ , we construct a simple, convex polytope, dubbed graph-associahedra , whose face poset is based on the connected subgraphs of Γ . This provides a natural generalization ofExpand
ABHY Associahedra and Newton polytopes of $F$-polynomials for finite type cluster algebras
A new construction of the associahedron was recently given by Arkani-Hamed, Bai, He, and Yan in connection with the physics of scattering amplitudes. We show that their construction (suitablyExpand

Generalized associahedra from the geometry of finite reflection groups
Permutahedra and generalized associahedra are a class of convex polytopes arising naturally from the study of finite reflection groups, and the intimate links those two classes of poly topes share are presented. Expand
Which nestohedra are removahedra
A removahedron is a polytope obtained by deleting inequalities from the facet description of the classical permutahedron. Relevant examples range from the associahedra to the permutahedron itself,Expand

A compatibility degree is defined that the compatibility vectors of all tubes of a graph "$G$ with respect to an arbitrary maximal tubing on $G$ support a complete simplicial fan realizing the nested complex of $G$. Expand

Faces of Generalized Permutohedra
The aim of the paper is to calculate face numbers of simple generalized permutohedra, and study their f-, h- and γ- vectors. These polytopes include permutohedra, associahedra, graph- associahedra,Expand
