On finiteness of the N-dimensional Hopf C*-algebras
Résumé
Given an algebraically closed field $k$ and an integer $N$, D. \c Stefan has proved that there exists only a finite number of Hopf $k$-algebras which are both semi-simple and co-semi-simple. In the C$^*$--algebraic framework, we provide in this note explicit upper-bounds for the number of Hopf C$^*$--algebra structures on a given finite dimensional C$^*$--algebra.
