该文研究了群缠绕模范畴怎样构造成张量范畴,给出的充分条件是要求群缠绕模中的代数和群余代数分别是双代数和半-Hopf群余代数,并满足一些相容条件.作者在张量群缠绕模范畴上构造了辫子.该文结果包括了拟三角和余拟三角Hopf代数(Hopf群余代数),Doi-Hopf群模等情况.
The authors investigate how the category of group entwined modules can be made into a monoidal category.It suffices that the algebra and 7r-coalgebra in question are bialge- bra and semi-Hopf 7r-coalgebra,with some extra compatibility relation.Braidings on a monoidal category of 7r-entwined modules are constructed.The construction unifies quasitriangular and coquasitriangular Hopf algebras(Hopfπ-coalgebras),Doi-Hopfπ-modules.
