论文摘要
我们构建了第二种Virasoro代数的汇合结合块。我们还构建了stokes变换，这些转换将一个块中的此类块映射到另一个扇区。在BPZ极限中，我们明确验证构造的块和相关的Stokes转换分别减少到汇合BPZ方程的解和其Stokes矩阵的解决方案。汇合的共形块和Stokes转换都是通过采用四点Virasoro共形块的交叉变换的合适汇合极限来构建的。
We construct confluent conformal blocks of the second kind of the Virasoro algebra. We also construct the Stokes transformations which map such blocks in one Stokes sector to another. In the BPZ limit, we verify explicitly that the constructed blocks and the associated Stokes transformations reduce to solutions of the confluent BPZ equation and its Stokes matrices, respectively. Both the confluent conformal blocks and the Stokes transformations are constructed by taking suitable confluent limits of the crossing transformations of the four-point Virasoro conformal blocks.
