Posh Parking Spaces

Jason Stack, Nathan Williams

Let $W$ be an irreducible complex reflection group with reflection representation $V$ . A $W$ -stable, faithful homogeneous system of parameters $Θ \subseteq Sym (V^{*})$ of com…

Parking Spaces for Complex Reflection Groups

Jason Stack

We answer an open problem of arXiv:1204.1760 and arXiv:1205.4293, extending their work to irreducible well--generated complex reflection groups $W$ . We define a combinatorial $W$ -n…

An elaborate new proof of Cayley's formula

Esther Banaian, Anh Trong Nam Hoang, Elizabeth Kelley +4

We construct a bijection between certain Deodhar components of a braid variety constructed from an affine Kac-Moody group of type $A_{n - 1}$ and vertex-labeled trees on $n$ vertices…
