BCJ, worldsheet quantum algebra and KZ equations

Chih-Hao Fu, Yihong Wang

摘要:

利用扭曲同调与量子群的对应关系,构造了开弦运动分子的代数解释。在这种情况下,表示依赖于字符串模式,因此,分子的上同调内容,以及穿孔的位置。我们发现,量子群根系统,从而确定了帮助确定Casimir出现在Knizhnik-Zamolodchikov连接,它可以用来相关的表示与不同的穿刺位置。

英文摘要:

We exploit the correspondence between twisted homology and quantum group to construct an algebra explanation of the open string kinematic numerator. In this setting the representation depends on string modes, and therefore the cohomology content of the numerator, as well as the location of the punctures. We show that quantum group root system thus identified helps determine the Casimir appears in the Knizhnik-Zamolodchikov connection, which can be used to relate representations associated with different puncture locations.
