拓扑对称Orbifold

The Topological Symmetric Orbifold

Songyuan Li, Jan Troost

摘要:

本文分析了复曲面M的对称积上的拓扑轨道共形场论。利用数学文献证明了算子环的标准商具有由Hurwitz数给出的结构常数。这证明了物理学文献中关于极值算子的一个猜想。此外,它允许利用对称群的组合学结果来显式计算更多的结构常数。我们还记得,全orbifold手征环是由对称orbifold Frobenius代数给出的。这种构造使得能够计算拓扑亏格为零和亏格为一的算子,并证明了更高亏格贡献的消失。所有拓扑映射的有效描述为拓扑AdS/CFT对应的证明奠定了基础。事实上,我们提出了一个具体的数学化身的证明,有关Gromow-威滕理论的散装量子上同调的边界上的希尔伯特计划。

英文摘要:

We analyse topological orbifold conformal field theories on the symmetric product of a complex surface M. By exploiting the mathematics literature we show that a canonical quotient of the operator ring has structure constants given by Hurwitz numbers. This proves a conjecture in the physics literature on extremal correlators. Moreover, it allows to leverage results on the combinatorics of the symmetric group to compute more structure constants explicitly. We recall that the full orbifold chiral ring is given by a symmetric orbifold Frobenius algebra. This construction enables the computation of topological genus zero and genus one correlators, and to prove the vanishing of higher genus contributions. The efficient description of all topological correlators sets the stage for a proof of a topological AdS/CFT correspondence. Indeed, we propose a concrete mathematical incarnation of the proof, relating Gromow-Witten theory in the bulk to the quantum cohomology of the Hilbert scheme on the boundary.
