摘要本文给出了余拟Hopf代数,在α是不可逆情况下日成为coribbon余拟Hopf代数的一个充要条件,并给出了辫子余拟Hopf代数上的Radford S^4公式. In this note,we will show a sufficient and necessary condition for a braided coquasi-Hopf algebra to H be coribbon,even if α ∈ H is not invertible,and give the Radford＇s S4 formula for a braided coquasi-Hopf algebra.
