摘要:

研究了开拓扑弦和闭拓扑弦在可分解锥及其镜像上的非微扰量子几何。我们的工具是有限差分方程的开放和封闭的字符串模和复苏分析其正式的幂级数的解决方案。在封闭的设置,我们得到新的有限差分方程的细化配分函数以及它的Nekrasov-Shatashvili(NS)极限。我们写下一个杰出的解析解的精细差分方程,重现预期的非微扰内容的精细拓扑弦。我们比较这个解决方案的自由能在NS限制的Borel分析。我们发现,博雷尔变换的奇点在于无限多的射线在博雷尔平面和斯托克斯跳跃跨越这些射线编码相关的唐纳森-托马斯不变量的基础Calabi-Yau几何。在开放设置中,有限差分方程对应于镜像曲线的正则量子化。我们使用Borel分析和精确WKB技术分析了这个差分方程,并在相应的指数谱网络中识别了5d BPS态。此外,我们涉及的复苏分析在开放和封闭的设置。这引导我们到一个五维扩展的Nekrasov-Rosly-Shatashvili建议,其中NS自由能计算作为一个生成函数的$q$ -差opers在一组特殊的光谱坐标。最后,我们研究了描述相应的量子可积系统的两个谱问题。

英文摘要:

We study the non-perturbative quantum geometry of the open and closed topological string on the resolved conifold and its mirror. Our tools are finite difference equations in the open and closed string moduli and the resurgence analysis of their formal power series solutions. In the closed setting, we derive new finite difference equations for the refined partition function as well as its Nekrasov-Shatashvili (NS) limit. We write down a distinguished analytic solution for the refined difference equation that reproduces the expected non-perturbative content of the refined topological string. We compare this solution to the Borel analysis of the free energy in the NS limit. We find that the singularities of the Borel transform lie on infinitely many rays in the Borel plane and that the Stokes jumps across these rays encode the associated Donaldson-Thomas invariants of the underlying Calabi-Yau geometry. In the open setting, the finite difference equation corresponds to a canonical quantization of the mirror curve. We analyze this difference equation using Borel analysis and exact WKB techniques and identify the 5d BPS states in the corresponding exponential spectral networks. We furthermore relate the resurgence analysis in the open and closed setting. This guides us to a five-dimensional extension of the Nekrasov-Rosly-Shatashvili proposal, in which the NS free energy is computed as a generating function of $q$-difference opers in terms of a special set of spectral coordinates. Finally, we examine two spectral problems describing the corresponding quantum integrable system.
