AI总结:

本文提出3d-5d指数网络与差分方程精确WKB的联系,证明差分方程局部解在Borel平面的奇点对应BPS KK模中心荷,并通过C^3和解析conifold示例验证局部解跳跃行为及其与非微扰拓扑弦振幅的关联。

摘要:

我们提出3d-5d指数网络与差分方程精确WKB之间的联系,这些差分方程与五维Seiberg-Witten曲线或环面Calabi-Yau三流形X的量子镜曲线相关联:此类差分方程局部解在Borel平面上的奇点对应于3d-5d BPS KK模的中心荷。由此可知,在指数网络补图的每个区域中应存在差分方程的特定局部解,且这些解在网络壁处发生跳跃。我们在两个简单的3d-5d系统示例中验证并探索了这一图景,对应于将环面Calabi-Yau X取为C^3或解析conifold。我们提供了Borel平面每个扇区及指数网络补图每个区域中局部解的完整列表,发现不连通区域中的局部解对应于X上带有位于环面图不同位置brane插入的非微扰开拓扑弦振幅。我们还研究了X上闭refined拓扑弦自由能的Borel求和及相应的非微扰效应,发现5d BPS KK模的中心荷与Borel平面中的奇点相关。

英文摘要:

We propose a connection between 3d-5d exponential networks and exact WKB for difference equations associated to five dimensional Seiberg-Witten curves, or equivalently, to quantum mirror curves to toric Calabi-Yau threefolds $X$: the singularities in the Borel planes of local solutions to such difference equations correspond to central charges of 3d-5d BPS KK-modes. It follows that there should be distinguished local solutions of the difference equation in each domain of the complement of the exponential network, and these solutions jump at the walls of the network. We verify and explore this picture in two simple examples of 3d-5d systems, corresponding to taking the toric Calabi-Yau $X$ to be either $\mathbb{C}^3$ or the resolved conifold. We provide the full list of local solutions in each sector of the Borel plane and in each domain of the complement of the exponential network, and find that local solutions in disconnected domains correspond to non-perturbative open topological string amplitudes on $X$ with insertions of branes at different positions of the toric diagram. We also study the Borel summation of the closed refined topological string free energy on $X$ and the corresponding non-perturbative effects, finding that central charges of 5d BPS KK-modes are related to the singularities in the Borel plane.
