局部空间上的拓扑规范理论与黑洞熵计数

Topological Gauge Theories on Local Spaces and Black Hole Entropy Countings

G. Bonelli, A. Tanzini

摘要:

研究复流形上全纯线丛全空间上的上同调规范理论,利用路径积分的U(1)等变局部化,得到了它们在基流形上的约化.我们通过精确的路径积分局部化证明了这种一般机制,减少了在hep-th/0411280中描述的局部曲线,与黑洞熵/Gromov-Witten不变量的计算有关。与四维规范理论的协议是恢复考虑在后者的非平凡的贡献,来自单圈波动决定因素的边界处的总空间。我们还研究了一类卡-丘局部曲面上的阿贝尔规范理论,描述了A模型的量子泡沫,与Donaldson-Thomas不变量的计算有关。

英文摘要:

We study cohomological gauge theories on total spaces of holomorphic line bundles over complex manifolds and obtain their reduction to the base manifold by U(1) equivariant localization of the path integral. We exemplify this general mechanism by proving via exact path integral localization a reduction for local curves conjectured in hep-th/0411280, relevant to the calculation of black hole entropy/Gromov-Witten invariants. Agreement with the four-dimensional gauge theory is recovered by taking into account in the latter non-trivial contributions coming from one-loop fluctuations determinants at the boundary of the total space. We also study a class of abelian gauge theories on Calabi-Yau local surfaces, describing the quantum foam for the A-model, relevant to the calculation of Donaldson-Thomas invariants.
