5D Nekrasov函数的q-顶点算子

q-Vertex Operator from 5D Nekrasov Function

Hiroshi Itoyama, Takeshi Oota, Reiji Yoshioka

摘要:

五维AGT对应关系暗示了q变形Virasoro块和5d Nekrasov配分函数之间的联系。本文从5维Nekrasov函数出发,确定了库仑气体表象中四点块的q-变形,并得到了q-变形顶点算子的表达式。如果我们只使用一种q-顶点算子,则必须修改它们的插入点之一以保持2d/5d对应。

英文摘要:

The five dimensional AGT correspondence implies the connection between the q-deformed Virasoro block and the 5d Nekrasov partition function. In this paper, we determine a q-deformation of the four-point block in the Coulomb gas representation from the 5d Nekrasov function, and obtain an expression of the q-deformed vertex operator. If we use only one kind of the q-vertex operators, one of the insertion points of them must be modified in order to hold the 2d/5d correspondence.
