| Abstract: |
| In this paper, we study Lazy 2-cocycle on Radford's biproduct Hom-Hopf algebra. By using twisting method, we mainly investigate the relations between the left Hom-2-cocycles σ on (B, β) and σ on (B×#H, β⊗α) which generalise the corresponding results in the case of usual Hopf algebras. |
