带边界的FZZ对偶

The FZZ duality with boundary

Thomas Creutzig, Yasuaki Hikida, Peter B. Ronne

摘要:

Fateev-Zamolodchikov-Zamolodchikov(FZZ)对偶将威滕的雪茄模型与正弦-刘维理论联系起来。这种对偶性在路径积分公式中得到了证明,并由Schomerus和作者之一推广到了高亏格闭黎曼曲面的情况。本文将对偶性进一步推广到有边界的情形。具体来说,我们将雪茄模型中的D1-膜与正弦-刘维尔理论中的D2-膜联系起来。特别地,我们构造了sine-Liouville理论中D2-膜的边界作用。我们还考虑了FZZ对偶的费米子版本。这种对偶性被证明是一个镜像对称的Hori和Kapustin,但我们给出了另一种证明的路径积分公式直接关系到关联函数。本文还研究了有边界的情形,所得结果与Hosomichi关于N=2超Liouville场论中膜的结果一致.

英文摘要:

The Fateev-Zamolodchikov-Zamolodchikov (FZZ) duality relates Witten's cigar model to sine-Liouville theory. This duality was proven in the path integral formulation and extended to the case of higher genus closed Riemann surfaces by Schomerus and one of the authors. In this note we further extend the duality to the case with boundary. Specifically, we relate D1-branes in the cigar model to D2-branes in the sine-Liouville theory. In particular, the boundary action for D2-branes in the sine-Liouville theory is constructed. We also consider the fermionic version of the FZZ duality. This duality was proven as a mirror symmetry by Hori and Kapustin, but we give an alternative proof in the path integral formulation which directly relates correlation functions. Also here the case with boundary is investigated and the results are consistent with those for branes in N=2 super Liouville field theory obtained by Hosomichi.
