SUMMARY:Algebraic Combinatorics Seminar - Aram Dermenjian
CLASS:PUBLIC
DESCRIPTION:TITLE: Sign variations and descents\n\nSpeaker:\n Aram Dermenj
 ian\n\nAffiliation:\n York University\n\nZoom:\n Contact Karen Yeats\n\nAB
 STRACT:\n\nIn this talk we consider a poset structure on projective sign v
 ectors.\nWe show that the order complex of this poset is partitionable and
  give\nan interpretation of the h-vector using type B descents of the type
  D\nCoxeter group.
