Representation theory of the Drinfeld doubles of a family of Hopf algebras II: corrections and new results
Résumé
We return to the fusion rules for the Drinfeld double of the duals of the generalised Taft algebras that we studied in [Erdmann et al., J. Pure Appl. Algebra 2006]. We first correct some proofs and statements in [Erdmann et al., J. Pure Appl. Algebra 2006] that were incorrect, using stable homomorphisms. We then complete this with new results on fusion rules for the modules we had not studied in [Erdmann et al., J. Pure Appl. Algebra 2006] and a classification of endotrivial and algebraic modules.
