SUMMARY:Algebraic Combinatorics Seminar - Loïc Foissy
CLASS:PUBLIC
DESCRIPTION:TITLE:Twisted Hopf algebras\n\nSpeaker:\n Loïc Foissy\n\nAffil
 iation:\n Université du Côte d'Opale\n\nZoom:\n Contact Karen Yeats\n\nA
 BSTRACT:\n\nA twisted Hopf algebra is a Hopf algebra in the category of li
 near\nspecies. The Fock functors allow to recover \"classical\" Hopf algeb
 ras\nfrom twisted ones. Numerous constructions and results can be lifted t
 o\nthe level of twisted bialgebras\, such that cofreeness\, shuffle and\nq
 uasi-shuffles products\, etc.
