Non-Perturbative Corrections to 3d BPS Indices and Topological Strings

Hans Jockers

AI总结:

本文通过SL(2,Z)变换Birkhoff连接矩阵捕捉三维GLSM的非微扰修正,并证明已解锥上二维GLSM的三维提升可作为非微扰拓扑弦的世界体积对偶,其微扰指标计算GV配分函数,解析延拓匹配非微扰完备化提议。

摘要:

对于由Kähler流形X参数化的三维规范线性sigma模型,三维BPS指标定义了一个q级数,可通过标准方法在Kähler模量中进行解析延拓。本文论证了Birkhoff连接矩阵的SL(2,Z)变换捕捉了三维GLSM的非微扰修正。作为应用,针对已解锥的标准二维GLSM的三维提升被证明为非微扰拓扑弦在已解锥上的世界体积对偶。微扰三维BPS指标计算Gopakumar-Vafa配分函数,而解析延拓则与已有的拓扑弦非微扰完备化提议相符。

英文摘要:

For a 3d gauged linear sigma model parametrized by a Kahler manifold X, the 3d BPS index defines a q-series that can be analytically continued in the Kahler modulus by standard methods. It is argued that an SL(2,Z)-transform of the Birkhoff connection matrix captures non-perturbative corrections to the 3d GLSM. As an application, a 3d lift of the standard 2d GLSM for the resolved conifold is shown to provide a world-volume dual for the non-perturbative topological string on the resolved conifold. The perturbative 3d BPS index computes the Gopakumar-Vafa partition function, while the analytic continuation matches existing proposals for a non-perturbative completion of the topological string.
