Wu-Yen Chuang

AI总结:

本文研究了resolved conifold上refined Donaldson-Thomas理论确定的量子Riemann-Hilbert问题,利用多重正弦函数给出显式解,并通过大N弦对偶性发现该解为拓扑弦和Donaldson-Thomas理论提供了非微扰定义。

摘要:

我们研究了由resolved conifold上的refined Donaldson-Thomas理论确定的量子Riemann-Hilbert问题。利用Beidgeland对经典Riemann-Hilbert问题的解,我们给出了具有不等参数的多重正弦函数形式的显式解。该解的新特征是,量子参数 $q^{\frac{1}{2}}=\exp(πi τ)$ 的有效区域在稳定性条件空间和BPS $t$-平面上变化。将解与refined Chern-Simons理论的配分函数进行比较,并应用大 $N$ 弦对偶性,我们发现该解包含了resolved conifold上refined拓扑弦的非微扰完备化。因此,求解量子Riemann-Hilbert问题为Donaldson-Thomas理论提供了一种可能的非微扰定义。

英文摘要:

We study the quantum Riemann-Hilbert problems determined by the refined Donaldson-Thomas theory on the resolved conifold. Using the solutions to classical Riemann-Hilbert problems by Beidgeland, we give explicit solutions in terms of multiple sine functions with unequal parameters. The new feature of the solutions is that the valid region of the quantum parameter $q^{\frac{1}{2}}=\exp(πi τ)$ varies on the space of stability conditions and BPS $t$-plane. Comparing the solutions with the partition function of refined Chern-Simons theory and invoking large $N$ string duality, we find that the solution contains the non-perturbative completion of the refined topological string on the resolved conifold. Therefore solving the quantum Riemann-Hilbert problems provides a possible non-perturbative definition for the Donaldson-Thomas theory.
