晶体交换子与Drinfeld的么正化R矩阵

The crystal commutor and Drinfeld's unitarized R-matrix

Joel Kamnitzer, Peter Tingley

摘要:

Drinfeld对任意量子群U_q(g)定义了一个酉化R-矩阵。这给出了U_q(g)表示范畴的一个交换子,使之成为一个上边界范畴. Henriques和Kamnitzer定义了另一个交换子,它也给了U_q(g)表示上边界范畴的结构.我们表明,一个特殊的情况下,Henriques和Kamnitzer的建设同意德林费尔德的交换。然后,我们描述的作用Drinfeld的交换对张量积的两个晶体基地,并解释的关系,晶体交换。

英文摘要:

Drinfeld defined a unitarized R-matrix for any quantum group U_q(g). This gives a commutor for the category of U_q(g) representations, making it into a coboundary category. Henriques and Kamnitzer defined another commutor which also gives U_q(g) representations the structure of a coboundary category. We show that a particular case of Henriques and Kamnitzer's construction agrees with Drinfeld's commutor. We then describe the action of Drinfeld's commutor on a tensor product of two crystal bases, and explain the relation to the crystal commutor.
