  • Generalized associahedra via brick polytopes 
    Pilaud, Vincent; Stump, Christian (Nancy : French Association for Discrete Mathematics & Theoretical Computer Science, 2012)
    We generalize the brick polytope of V. Pilaud and F. Santos to spherical subword complexes for finite Coxeter groups. This construction provides polytopal realizations for a certain class of subword complexes containing ...
  • Multi-cluster complexes 
    Ceballos, Cesar; Labbé, Jean-Philippe; Stump, Christian (Nancy : French Association for Discrete Mathematics & Theoretical Computer Science, 2012)
    We present a family of simplicial complexes called multi-cluster complexes. These complexes generalize the concept of cluster complexes, and extend the notion of multi-associahedra of types A and B to general finite Coxeter ...
  • On the combinatorics of Tits arrangements 
    Geis, David (Hannover : Institutionelles Repositorium der Leibniz Universität Hannover, 2018)
    In this thesis, we study simplicial arrangements of hyperplanes. Classically, a simplicial arrangement $\mathcal{A}$ in $\mathbb{R}^r$ is a finite set of linear hyperplanes such that every component of $\mathbb{R}^r \setminus ...
