辫子余拟Hopf代数的反对极

On the Antipode of Braided Coquasi-Hopf

设A是域上的一个辫子余拟Hopf代数,讨论了A的结构性质,尤其证明了辫子余拟Hopf代数A上的反对极(antipode)是双射,从而推广了日本数学家Doi的主要结果.

Let A be a braided coquasi-Hopf algebra over a field. Then we discuss a structure property on A , in particular, we show that the antipode S of A is bijective, generalizing the main result of Doi of Japanese mathemathtician.
