Let (H, a) be a monoidal Hom-bialgebra and (B,p) be a left (H, a)-Hom-comodule coalgebra. The new monoidal Hom-algebra B#y H is constructed with a Hom-twisted product Ba[H] and a. B × H Hom-smash coproduct. M...

We develop the Radford's biproduct theorem which plays an important role in giving a negative answer to a conjecture of I Kaplansky. Let B, H be two Hopf algebras with H acting weakly on B and α, β : B → H H be two...

Let (C, C) be a braided monoidal category. The relationship between the braided Lie algebra and the left Jacobi braided Lie algebra in the category (C, C) is investigated. First, a braided C2-commutative algebra i...

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.

We investigate the Morita context and graded cases for weak group corings and derive some equivalent conditions for p to be surjective. Furthermore, we develop Galois theory for weak group corings. As an application, ...
