On root posets for noncrystallographic root systems
Michael Cuntz, Christian Stump
We discuss properties of root posets for finite crystallographic root systems, and show that these properties uniquely determine root posets for the noncrystallographic dihedral ty…
Counting factorizations of Coxeter elements into products of reflections
Guillaume Chapuy, Christian Stump
In this paper, we count factorizations of Coxeter elements in well-generated complex reflection groups into products of reflections. We obtain a simple product formula for the expo…
Vertex barycenter of generalized associahedra
Vincent Pilaud, Christian Stump
We show that the vertex barycenter of generalized associahedra and permutahedra coincide for any finite Coxeter system.
EL-labelings and canonical spanning trees for subword complexes
Vincent Pilaud, Christian Stump
We describe edge labelings of the increasing flip graph of a subword complex on a finite Coxeter group, and study applications thereof. On the one hand, we show that they provide c…
