漩涡的刘维尔一侧
The Liouville side of the Vortex
摘要:
我们分析了Liouville/Toda共形场论中多个(半)简并场插入的共形块,并证明了它们的矢量空间完全由开拓扑弦振幅的四维极限再现,而开拓扑弦振幅的四维极限具有与合适的规范规范理论相关联的一般边界条件.作为副产品,我们确定了非阿贝尔涡旋配分函数与退化共形块的特定融合通道。
英文摘要:
We analyze conformal blocks with multiple (semi-)degenerate field insertions in Liouville/Toda conformal field theories an show that their vector space is fully reproduced by the four-dimensional limit of open topological string amplitudes on the strip with generic boundary conditions associated to a suitable quiver gauge theory. As a byproduct we identify the non-abelian vortex partition function with a specific fusion channel of degenerate conformal blocks.
