We present a new family of simplicial complexes called multi-cluster complexes. These complexes generalize the concept of cluster complexes, and extend the notion of multi-associahedra to arbitrary finite Coxeter groups.
We present combinatorial and geometric properties of these objects, as well as open problems and conjectures.
This is joint work with Jean-Philippe Labbé and Christian Stump
