SUMMARY:Algebraic Combinatorics Seminar - Aram Dermenjian
CLASS:PUBLIC
DESCRIPTION:Summary \n\nTITLE: Sign variations and descents\n\nSpeaker:\n 
 Aram Dermenjian\n\nAffiliation:\n York University\n\nZoom:\n Contact Karen
  Yeats\n\nABSTRACT:\n\nIn this talk we consider a poset structure on proje
 ctive sign vectors.\nWe show that the order complex of this poset is parti
 tionable and give\nan interpretation of the h-vector using type B descents
  of the type D\nCoxeter group.\n
