  • 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 ...
  • Triangle density and contractibility 
    Kriesell, Matthias (Cambridge : Cambridge University Press, 2005)
    Let G be a noncomplete k -connected graph such that the graphs obtained from contracting any edge in G are not k-connected, and let t(G) denote the number of triangles in G. Thomassen proved t(G) ≥ 1, which was later ...
