文摘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).
