论文摘要
我们使用字符串场理论的见解来分析和治愈最小弦理论中的圆柱图中的差异，两个边界都位于ZZ Brane上。我们专注于世界表格问题的理论，包括$（2，p）$最小模型加上liouville理论，以及总收费26，以及通常的$ bc $ ghosts。弦场理论过程给出了最小的弦理论中非扰动效应的有限的，纯粹的假归一化常数，或者在JT重力中具有双扰动效应。我们发现与双重双尺度一矩阵积分的预测相关的确定性。我们还对此结果的扩展为更通用的$（p'，p）$最小字符串发表了一些评论。
We use insights from string field theory to analyze and cure the divergences in the cylinder diagram in minimal string theory with both boundaries lying on a ZZ brane. We focus on theories with worldsheet matter consisting of the $(2,p)$ minimal model plus Liouville theory, with total central charge 26, together with the usual $bc$-ghosts. The string field theory procedure gives a finite, purely imaginary normalization constant for non-perturbative effects in minimal string theory, or doubly non-perturbative effects in JT gravity. We find precise agreement with the prediction from the dual double-scaled one-matrix integral. We also make a few remarks about the extension of this result to the more general $(p',p)$ minimal string.
