关于sl3 Knizhnik-Zamolodchikov方程和W3零向量方程

On sl3 Knizhnik-Zamolodchikov equations and W3 null-vector equations

Sylvain Ribault

摘要:

本文从Sklyanin关于s1 ~ 3 Yangian模型的分离变量出发,导出了量子s1 ~ 3 Gaudin模型的分离变量。我们使用由此产生的新变量重写sl 3 Knizhnik-Zamolodchikov方程,并比较它们与某些零矢量方程的共形场论与W3-代数对称性。这两组方程非常相似,但只有在临界水平极限时才变得相同。这与s12 Knizhnik-Zamolodchikov方程相反,已知其对于所有能级值都等价于Belavin-Polyakov-Zamolodchikov方程。

英文摘要:

Starting from Sklyanin's separation of variables for the sl3 Yangian model, we derive the separation of variables for the quantum sl3 Gaudin model. We use the resulting new variables for rewriting the sl3 Knizhnik-Zamolodchikov equations, and comparing them with certain null-vector equations in conformal field theories with W3-algebra symmetry. The two sets of equations are remarkably similar, but become identical only in the critical level limit. This is in contrast to the sl2 Knizhnik-Zamolodchikov equations, which are known to be equivalent to Belavin-Polyakov-Zamolodchikov equations for all values of the level.
