Description

Andruskiewitsch and Schneider classify a large class of pointed Hopf algebras with abelian coradical. The quantum double of each such Hopf algebra is investigated. The quantum doubles of a family of Hopf algebras from the above classification are ribbon Hopf algebras.
Some details are added. Corollary 2.4 and the remark after it are reformulated. Section 4 with a general tareatment is added. References are updated
