顶点、涡和相互作用曲面算子

Vertices, Vortices & Interacting Surface Operators

Giulio Bonelli, Alessandro Tanzini, Jian Zhao

摘要:

本文证明了二维平面上具有伴随和反基本物质的非阿贝尔超对称N=(2,2)规范理论中的涡旋模空间可描述为四维瞬子模空间的全纯子流形.这些理论的涡配分函数通过等变局部化计算。我们表明,这些符合场论限制的拓扑顶点上的带与边界条件对应的柱形图。此外,我们还将顶点配分函数的场论极限归结为广义超几何函数,将其AGT对偶描述表示为简单型的相互作用曲面算子。类似地,我们恢复的拓扑开弦振幅的q-变形广义超几何函数证明他们满足适当的有限差分方程。

英文摘要:

We show that the vortex moduli space in non-abelian supersymmetric N=(2,2) gauge theories on the two dimensional plane with adjoint and anti-fundamental matter can be described as an holomorphic submanifold of the instanton moduli space in four dimensions. The vortex partition functions for these theories are computed via equivariant localization. We show that these coincide with the field theory limit of the topological vertex on the strip with boundary conditions corresponding to column diagrams. Moreover, we resum the field theory limit of the vertex partition functions in terms of generalized hypergeometric functions formulating their AGT dual description as interacting surface operators of simple type. Analogously we resum the topological open string amplitudes in terms of q-deformed generalized hypergeometric functions proving that they satisfy appropriate finite difference equations.
