摘要:

镜像曲线到复曲面Calabi-Yau三重的量子化导致迹类算子,并且已经证明,这些算子的谱性质提供了拓扑弦论在这些背景下的非微扰实现。本文利用Faddeev量子双对数,给出了局部P1 xP 1情形下迹类算子积分核的一种显式形式。与该积分核相关联的矩阵模型是O(2)模型,其推广了ABJ(M)矩阵模型。我们发现它的确切的平面极限,我们提供了详细的证据,它的1/N展开捕获所有属拓扑弦自由能本地P1 xP 1。

英文摘要:

The quantization of mirror curves to toric Calabi--Yau threefolds leads to trace class operators, and it has been conjectured that the spectral properties of these operators provide a non-perturbative realization of topological string theory on these backgrounds. In this paper, we find an explicit form for the integral kernel of the trace class operator in the case of local P1xP1, in terms of Faddeev's quantum dilogarithm. The matrix model associated to this integral kernel is an O(2) model, which generalizes the ABJ(M) matrix model. We find its exact planar limit, and we provide detailed evidence that its 1/N expansion captures the all genus topological string free energy on local P1xP1.
