Given any finite simplicial complex Delta, we show how to construct from a colouring chi of Delta a new simplicial complex Delta(chi) that is balanced and vertex decomposable. In addition, the h-vector of Delta(chi) is precisely the f-vector of Delta. Our construction generalizes the "whiskering" construction of Villarreal, and Cook and Nagel. We also reverse this construction to prove a special case of a conjecture of Cook and Nagel, and Constantinescu and Varbaro on the h-vectors of flag complexes. |
