SMASH COPRODUCTS OF MONOIDAL COMONADS AND HOM-ENTWINING STRUCTURES

摘要

Let F, G be monoidal comonads on a monoidal category C. The aim of this paper is to discuss the smash coproducts of F and G. As an application, the smash coproduct of Hom-bialgebras is discussed. Further, the Hom-entwining structure and Hom-entwined modules are investigated.
