The Hopf algebra structure of a crossed product in a braided monoidal category (Q1861076)

The authors derive conditions under which a tensor product \(A \otimes H\), in a braided monoidal category, along with a crossed product structure and a smash coproduct structure is a Hopf algebra. The authors also recover the classical theorem due to Radford characterizing the smash product algebra and the smash coproduct algebra to form a bialgebra.
