Abstract
We apply Majid's transmutation procedure to Hopf algebra maps , where is a compact abelian group, and explain how this construction gives rise to braided Hopf algebras over quotients of by subgroups that are cocentral in . This allows us to unify and generalize a number of recent constructions of braided compact quantum groups, starting from the braided quantum group, and describe their bosonizations.
