On Isomorphisms between Certain Yetter-Drinfel'd Hopf Algebras

Abstract

For two families of Yetter-Drinfel'd Hopf algebras considered earlier by the authors, we determine which of them are isomorphic. We also determine which of their Radford biproducts are isomorphic.Comment: 23 pages. In the second version, the argument in Paragraph 1.5 has been simplified.
