For each poset P , we construct a polytope A (P ) called the P -associahedron. Similarly to the case of graph associahedra, the faces of A (P ) correspond to certain tubings of P . The Stasheff associahedron is a compactification of the configuration space of n points on a line, and we recover A (P ) as an analogous compactification of the space of order-preserving maps P → R. Motivated by the study of totally nonnegative critical varieties in the Grassmannian, we introduce affine poset…

Critical varieties in the Grassmannian
We introduce a family of spaces called critical varieties. Each critical variety is a subset of one of the positroid varieties in the Grassmannian. The combinatorics of positroid varieties is

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 of
Associahedron, cyclohedron and permutohedron as compactifications of configuration spaces
As in the case of the associahedron and cyclohedron, the permutohedron can also be defined as an appropriate compactification of a configuration space of points on an interval or on a circle. The

A transfer map allows us to transfer properties of ϑ(P) to ℒ(P), and to transfer known inequalities involving linear extensions ofP to some new inequalities.

TLDR
It is proved that Σn is isomorphic to the boundary complex of some (n − 3)-dimensional simplicial convexpolytope, and that this polytope can be geometrically realized to have the dihedral group Dn as its group of symmetries.
Convex polytopes from nested posets
TLDR
A new family of simple convex polytopes obtained by iterated truncations is led to, which generalize graph associahedra and nestohedra, even encompassing notions of nestings on CW-complexes.

TLDR
This work proposes a B-analogue of the associahedron, a simplicial polytope whose h- vector is given by the rank-sizes of the type-B noncrossing partition lattice, just as the h-vector of the (simplicial type-A) assocIAhedron isgiven by the Narayana numbers.
Arithmetic of Marked Order Polytopes, Monotone Triangle Reciprocity, and Partial Colorings
TLDR
The marked order polytope parametrizes the order preserving extensions of F to P and the function counting integral-valued extensions is a piecewise polynomial in F and a reciprocity statement is proved in terms of order-reversing maps.
Alcoved Polytopes, I
TLDR
The aim of this paper is to study alcoved polytopes, which are poly topes arising from affine Coxeter arrangements, and to give a combinatorial formula for volumes of thesepolytopes.
The type $B$ permutohedron and the poset of intervals as a Tchebyshev transform
We show that the order complex of intervals of a poset, ordered by inclusion, is a Tchebyshev triangulation of the order complex of the original poset. Besides studying the properties of this
Matroid polytopes, nested sets and Bergman fans
The tropical variety defined by linear equations with constant coefficients is the Bergman fan of the corresponding matroid. Building on a self-contained introduction to matroid polytopes, we present
