讨论了代数的简并场与Gaiotto对超共形规范理论中Seiberg-Witten曲线的描述的点之间的对应关系。也就是说，我们发现在一级零态的代数退化场的类型可以用带框的Young图来分类，并且Seiberg-Witten曲线在击穿附近的奇异行为与发生器的奇异行为一致。我们还发现了如何将规范理论的质量参数转化为户田理论的动量。
We discuss the correspondence between degenerate fields of thealgebra and punctures of Gaiotto’s description of the Seiberg-Witten curve ofsuperconformal gauge theories. Namely, we find that the type of degenerate fields of thealgebra, with null states at level one, is classified by Young diagrams withboxes, and that the singular behavior of the Seiberg-Witten curve near the puncture agrees with that ofgenerators. We also find how to translate mass parameters of the gauge theory to the momenta of the Toda theory.
