Decoupling of Tensor factors in Cross Product and Braided Tensor Product Algebras
Abstract
We briefly review and illustrate our procedure to 'decouple' by transformation of generators: either a Hopf algebra H from a H-module algebra A1 in their cross-product A1 > H; or two (or more) H-module algebras A1,A2. These transformations are based on the existence of an algebra map A1 > H A1.
