We obtain the necessary and sufficient conditions for Radford's biproduct to be a braided Hopf algebra. As an application, a nontrivial example is given.

Let (H,β) be a Hom-bialgebra such that β^2 = idH. (A, αA) is a Hom-bialgebra in the left-left Hom-Yetter-Drinfeld category H^HYD and (B, αB) is a Hom-bialgebra in the right-right Hom-Yetter-Drinfeld category...Let (H,β) be a Hom-bialgebra such that β^2 = idH. (A, αA) is a Hom-bialgebra in the left-left Hom-Yetter-Drinfeld category H^HYD and (B, αB) is a Hom-bialgebra in the right-right Hom-Yetter-Drinfeld category YDH^H. The authors define the two-sided smash product Hom-algebra (A H B, αA β αB) and the two-sided smash coproduct Hom- coalgebra (A H B, αA β αB). Then the necessary and sufficient conditions for (A H B, αA β αB) and (A H B, αA β αB) to be a Hom-bialgebra (called the double biproduct Hom-bialgebra and denoted by (A H B, αA β αB)) are derived. On the other hand, the necessary and sufficient conditions for the smash coproduct Hom-Hopf algebra (A H B, αA β) to be quasitriangular are given.展开更多
