SUMMARY:Algebraic Combinatorics Seminar - Christos Athanasiadis
CLASS:PUBLIC
DESCRIPTION:Summary \n\nTITLE: Face enumeration and real-rootedness\n\nSpe
 aker:\n Christos Athanasiadis\n\nAffiliation:\n University of Athens\n\nZo
 om:\n Contact Karen Yeats\n\nABSTRACT:\n\nAbout fifteen years ago F. Brent
 i and V. Welker showed that the face\nenumerating polynomial of the baryce
 ntric subdivision 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 whe
 n simplicial\ncomplexes are replaced by more general cell complexes.\n
