本文讨论双交叉积Hopf代数B^β△→←△αH的辫子结构。通过引进一些新的概念,给出并证明了双交叉积Hopf代数B^β△→←△αH构成辫子Hopf代数的充分条件与必要条件,同时给出了其辫子结构的分解形式。
The braided structure of the bicrossproduct Hopf algebra B^β△→←△αH is studied. By intro- ducing some new concepts, some necessary conditions and sufficient conditions for B^β△→←△αH to be a braided Hopf algebra are given, respectively. The decomposition of the braided structure is also given.
