ABSTRACT:

About fifteen years ago F. Brenti and V. Welker showed that the face
enumerating polynomial of the barycentric subdivision of any
Cohen-Macaulay simplicial complex has only real roots. It is natural
to ask whether similar results hold when barycentric subdivision is
replaced by more general types of triangulations, or when simplicial
complexes are replaced by more general cell complexes.
