SUMMARY:Algebraic Combinatorics Seminar - Christos Athanasiadis
CLASS:PUBLIC
DESCRIPTION:TITLE: Face enumeration and real-rootedness\n\nSpeaker:\n Chri
 stos Athanasiadis\n\nAffiliation:\n University of Athens\n\nZoom:\n Contac
 t Karen Yeats\n\nABSTRACT:\n\nAbout fifteen years ago F. Brenti and V. Wel
 ker showed that the face\nenumerating polynomial of the barycentric subdiv
 ision of any\nCohen-Macaulay simplicial complex has only real roots. It is
  natural\nto ask whether similar results hold when barycentric subdivision
  is\nreplaced by more general types of triangulations\, or when simplicial
 \ncomplexes are replaced by more general cell complexes.
