辫子余自由霍普夫代数与量子多支撑代数
Braided cofree Hopf algebras and quantum multi-brace algebras
摘要：
给出了辫余自由余代数上霍普夫代数结构的系统构造.相关的底层结构是辫代数和辫余代数。我们提供了这些代数和余代数与量子群有关的一些有趣的例子。我们引入量子多支撑代数作为自然框架，它是辫子代数和$\textbf{B}_\infty$ -代数的推广。这门新学科使人们能够用统一的方法来表示一些重要的代数结构。特别有趣的例子是量子拟洗牌代数。
英文摘要：
We give a systematic construction of Hopf algebra structures on braided cofree coalgebras. The relevant underlying structures are braided algebras and braided coalgebras. We provide some interesting examples of these algebras and coalgebras related to quantum groups. We introduce quantum multi-brace algebras which are generalizations of both braided algebras and $\textbf{B}_\infty$-algebras, as the natural framework. This new subject enables one to quantize some important algebra structures in a uniform way. Particular interesting examples are quantum quasi-shuffle algebras.
