Leclerc and Zelevinsky, motivated by the study of quasi-commuting quantum flag minors,
introduced the notions of strongly separated and weakly separated collections. These …

We use simplicial complexes to model weighted voting games where certain coalitions are
considered unlikely or impossible. Expressions for Banzhaf and Shapley-Shubik power …

The problem of deciding if a given triangulation of a sphere can be realized as the boundary
sphere of a simplicial, convex polytope is known as the 'Simplicial Steinitz problem'. It is …

We describe and study an explicit structure of a regular cell complex K (L) K (L) on the
moduli space M (L) of a planar polygonal linkage L. The combinatorics is very much related …

We explicitly describe a structure of a regular cell complex $ K (L) $ on the moduli space $ M
(L) $ of a planar polygonal linkage $ L $. The combinatorics is very much related (but not …

A configuration of a linkage Γ is a possible positioning of Γ in R d, and the collection of all
such forms the configuration space C (Γ) of Γ. We here introduce the notion of the symmetric …

Simplicial complexes K, which are equal to their Alexander dual KΛ are known as self-dual
simplicial complexes. We prove that topological and combinatorial properties of any self …

An Alexander self-dual complex gives rise to a compactification of\cal M _ 0, n ℳ 0, n, called
an ASD compactification, which is a smooth algebraic variety. ASD compactifications include …
