我们引入了半带状霍普夫代数的概念,这是一个带状霍普夫代数沿着与一个杰出的元素$t$对应的扭转带状180度(半扭转)。我们证明了U_q(g)是一个(拓扑)半带Hopf代数,但仅当使用一个修正的带元时.然后,我们讨论了使用这种修改后的带状元素的一些后果。
We introduce the notion of a half-ribbon Hopf algebra, which is a ribbon Hopf algebra along with a distinguished element $t$ corresponding to twisting a ribbon by 180 degrees (the half-twist). We show that U_q(g) is a (topological) half-ribbon Hopf algebra, but only if one uses a modified ribbon element. We then discuss some consequences of using this modified ribbon element.
