In a parallel manner we consider Hopf algebras with several objects, namely Hopf categories, which are always considered over a group instead of a set of objects. We will define Hopf structures and consider the Pierce decomposition of a Hopf algebra. The free case corresponds to Hopf quivers considered previously with Marc Rosso (J. of Algebra, 2002). This work\u2019s progress is towards the existence of a fundamental group of a Hopf category. For that purpose we will recall the Galois coverings of linear categories, and possible extensions to Hopf categories. This is joint work with Andrea Solotar (Buenos Aires).<\/p>\n","protected":false},"excerpt":{"rendered":"<p>A talk by Professor Claude Cibils from Universite de Montpellier on &#8220;Algebra Seminar&#8221; with following details.
