摘要:

我们提出一种方法,用于挑战二维共形场论(CFT$_2$)中带有$x$个边界算符的亏格-$g$、体$n$点、$b$边界、$c$交叉帽关联函数$\mathcal{F}_{g,n,b,c}^{x}$的计算。我们证明了$\mathcal{F}_{g,n,b,c}^{x}$是亏格-$g$、体$(n+b+c)$点函数$\mathcal{F}_{g,(n+b+c)}$的无限线性组合,并尝试在本工作中获得这些线性系数。我们证明了在退化极限下线性系数中存在单极点结构。获得无限线性系数的一种实用方法是Ishibashi态的自由场实现。我们回顾了Virasoro最小模型$\mathcal{M}(p,p')$中的结果,并将其推广到$N=1$最小模型$\mathcal{SM}(p,p')$。

英文摘要:

We propose a method to challenge the calculation of genus-$g$, bulk $n$-point, $b$-boundary, $c$-crosscap correlation functions with $x$ boundary operators $\mathcal{F}_{g,n,b,c}^{x}$ in two-dimensional conformal field theories (CFT$_2$). We show that $\mathcal{F}_{g,n,b,c}^{x}$ are infinite linear combinations of genus-$g$, bulk $(n+b+c)$-point functions $\mathcal{F}_{g,(n+b+c)}$, and try to obtain the linear coefficients in this work. We show the existence of a single pole structure in the linear coefficients at degenerate limits. A practical method to obtain the infinite linear coefficients is the free field realizations of Ishibashi states. We review the results in Virasoro minimal models $\mathcal{M}(p,p')$ and extend it to the $N=1$ minimal models $\mathcal{SM}(p,p')$.
