Liouville理论中的融合核

On fusion kernel in Liouville theory

Nikita Nemkov

摘要:

我们研究了Liouville理论中非退化共形块的融合核,作为五边形恒等式所产生的差分方程的解。我们提出了一种方法,这些方程的基础上“非微扰”系列扩展,允许迭代计算融合核。当中心荷为$c=1+6(b-b^{-1})^2$和$b~\in \mathbb{N}$时,我们也找到了精确解.对于$c = 1$,我们的结果再现了早先通过潘勒韦方程从解析延拓中得到的公式。然而,在我们的例子中,它以显着简化的形式出现。

英文摘要:

We study fusion kernel for non-degenerate conformal blocks in Liouville theory as a solution to the difference equations originating from the pentagon identity. We suggest an approach to these equations based on 'non-perturbative' series expansion which allows to calculate the fusion kernel iteratively. We also find the exact solutions for the cases when the central charge is $c=1+6(b-b^{-1})^2$ and $b~\in \mathbb{N}$. For $c = 1$ our result reproduces the formula, obtained earlier from analytical continuation via Painlevé equation. However, in our case it appears in a significantly simplified form.
