Realizing the associahedron: Mysteries and questions
Cesar Ceballos, Günter M. Ziegler
There are many open problems and some mysteries connected to the realizations of the associahedra as convex polytopes. In this note, we describe three -- concerning special realiza…

Many non-equivalent realizations of the associahedron
Cesar Ceballos, Francisco Santos, Günter M. Ziegler
Hohlweg and Lange (2007) and Santos (2004, unpublished) have found two different ways of constructing exponential families of realizations of the n-dimensional associahedron with n…

Projecting lattice polytopes without interior lattice points
Benjamin Nill, Günter M. Ziegler
We show that up to unimodular equivalence there are only finitely many d-dimensional lattice polytopes without interior lattice points that do not admit a lattice projection onto a…
