Igor Frenkel, Minxian Zhu

摘要:

基于Belavin-Polyakov-Zamolodchikov方程,给出了Virasoro代数的修正正则表示所对应的一类秩为$26$的顶点算子代数的抽象构造.利用Virasoro代数对的交织算子的张量积得到顶点算子。我们明确确定的结构系数,产生的公理VOA。在构造过程中,我们得到了新的超几何恒等式。

英文摘要:

We give an abstract construction, based on the Belavin-Polyakov-Zamolodchikov equations, of a family of vertex operator algebras of rank $26$ associated to the modified regular representations of the Virasoro algebra. The vertex operators are obtained from the tensor products of intertwining operators for a pair of Virasoro algebras. We explicitly determine the structure coefficients that yield the axioms of VOAs. In the process of our construction, we obtain new hypergeometric identities.
