Résumé
Abstract

Soit G un groupe sporadique différent du groupe de Fischer ${Fi}_{22}$ , du bébé monstre B et du monstre M. Soit H une algèbre de Hopf complexe pointée de dimension finie dont le groupe des éléments dont le co-produit est égal au carré tensoriel est isomorphisme à G, alors H est isomorphe a l'algèbre de groupe de G.

Any finite-dimensional complex pointed Hopf algebra with group of group-likes isomorphic to a sporadic group, with the possible exception of the Fischer group ${Fi}_{22}$ , the Baby Monster B and the Monster M, is a group algebra.
