The Gaussian coefficient revisited

Richard Ehrenborg, Margaret A. Readdy

We give a new $q$ - $(1 + q)$ -analogue of the Gaussian coefficient, also known as the $q$ -binomial which, like the original $q$ -binomial $[k n]_{q}$ , is symmetric…

Simion's type $B$ associahedron is a pulling triangulation of the Legendre polytope

Richard Ehrenborg, Gabor Hetyei, Margaret Readdy

We show that Simion's type $B$ associahedron is combinatorially equivalent to a pulling triangulation of a type $B$ root polytope called the Legendre polytope. Furthermore, we show…

The van der Waerden complex

Richard Ehrenborg, Likith Govindaiah, Peter S. Park +1

We introduce the van der Waerden complex $vdW (n, k)$ defined as the simplicial complex whose facets correspond to arithmetic progressions of length $k$ in the vertex set $\{1,…
