Title: Face enumeration and real-rootedness

Speaker: Christos Athanasiadis Affiliation: University of Athens Zoom: Contact Karen Yeats

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.
