摘要:本文主要研究*-双代数及其对偶*-双代数的对合. 对于双代数 , 当A为无穷维时,不容易确定A\'中的元素,但是通过A的有限维表示可以构造A\'的子代数,这样就产生一个问题,这个子代数是否可以分离A中的点,基于上述原因,自然我们需要考虑*-双代数的对合. 关于一对双代数,Hopf代数,Hopf*-代 ...

摘要:本文选取Hopf代数和有限维离散量子群作为研究平台. \ 设$G$为离散群,其单位元为$e$.考察$G$上具有有限支撑的复值函数在点点相乘的意义下构成的代数$A$.$G$上乘法可通过定义$(\Delta f)(s,t)=f(st)(\forall f\in A, \ s,t\in G)$来诱导出$A ...
