SUMMARY:Algebraic Combinatorics Seminar - Yannic Vargas
CLASS:PUBLIC
DESCRIPTION:TITLE: Algebraic structure of the Hopf algebra of double poset
 s\n\nSpeaker:\n Yannic Vargas\n\nAffiliation:\n Potsdam University\n\nZoom
 :\n Contact Karen Yeats\n\nABSTRACT:\n\nA Hopf algebra of double posets wa
 s introduced by Claudia Malvenuto\nand Christophe Reutenauer in 2011\, mot
 ivated by the study of pictures\nof tableaux as defined by Zelevinsky. St
 arting from the correspondence\nbetween top-cones in the braid arrangement
  and partial orders\, we\ninvestigate several properties of the Hopf alge
 bra of double posets\nas the image of a Hopf monoid (via the Fock functor
 ). In particular\,\nwe obtain a non-cancellative formula for the antipode.
  A description\nof the primitive space is also discussed.
