Abstract

In this paper, we mainly provide a new approache to construct Hom-Hopf algebras. For this, we introduce and study the notion of a left (m,k)(m,k)-Hom-crossed product structure as a generalization of kk-Hom-smash product structure. Then one combines this (m,k)(m,k)-Hom-crossed product structure and a left mm-Hom-smash coproduct structure to build Radford [(m,k),m][(m,k),m]-biproduct theorem. Finally, we study Hom admissible mappping system to characterize this Radford [(m,k),m][(m,k),m]-biproduct structure.
