The permuto-associahedron revisited

چکیده
A classic problem connecting algebraic and geometric combinatorics is the realization problem: given a poset, determine whether there exists polytope whose face lattice poset. In 1990s, Kapranov defined poset as hybrid between of permutohedron that an associahedron, he asked this realizable. Shortly after his question was posed, Reiner Ziegler provided realization. Based on our previous work nested braid fan, we provide in paper different Kapranov’s by constructing vertex set normal fan permuto-associahedron simultaneously.

The Multiple Facets of the Associahedron
This is a survey of some of the nice properties of the associahedron (also called Stasheff polytope) from several points of views: topological, geometrical, combinatorial and algebraic.
متن کاملFinite Earthquakes and the Associahedron
By using finite earthquakes, we show there exists a homeomorphism Φ between the real analytic Teichmüller space Tn of a set of n + 3 variable labelled points cyclically arranged on the unit circle and the interior of the n-dimensional associahedron Kn+2. We also show how to obtain the faces of a compactification T n of Tn by letting certain finite earthquake parameters approach ∞. The homeomorp...
متن کاملRational Catalan Combinatorics: The Associahedron
Each positive rational number x > 0 can be written uniquely as x = a/(b − a) for coprime positive integers 0 < a < b. We will identify x with the pair (a, b). In this extended abstract we use rational Dyck paths to define for each positive rational x > 0 a simplicial complex Ass(x) = Ass(a, b) called the rational associahedron. It is a pure simplicial complex of dimension a− 2, and its maximal ...
متن کاملFrom Permutahedron to Associahedron
For each finite real reflection group W , we identify a copy of the type-W simplicial generalised associahedron inside the corresponding simplicial permutahedron. This defines a bijection between the facets of the generalised associahedron and the elements of the type W non-crossing partition lattice which is more tractable than previous such bijections. We show that the simplicial fan determin...
متن کاملThe Discrete Fundamental Group of the Associahedron
The associahedron is an object that has been well studied and has numerous applications, particularly in the theory of operads, the study of non-crossing partitions, lattice theory and more recently in the study of cluster algebras. We approach the associahedron from the point of view of discrete homotopy theory, that is we consider 5-cycles in the 1-skeleton of the associahedron to be combinat...
