摘要:

本文研究了三球上N=2的超共形场论,分析了它们的自由能F随背景规范场和超引力场的变化。在这些背景领域中,某些地方术语起着至关重要的作用,包括几个陈-西蒙斯术语。这些项的存在澄清了F的一些微妙性质。这种理解使我们能够证明F最大化原理。这也解释了为什么通过局部化计算F会导致一个复杂的答案,即使我们期望它在酉理论中是真实的。我们讨论了几个推论,我们的结果和评论的关系的F-定理。

英文摘要:

We consider three-dimensional N=2 superconformal field theories on a three-sphere and analyze their free energy F as a function of background gauge and supergravity fields. A crucial role is played by certain local terms in these background fields, including several Chern-Simons terms. The presence of these terms clarifies a number of subtle properties of F. This understanding allows us to prove the F-maximization principle. It also explains why computing F via localization leads to a complex answer, even though we expect it to be real in unitary theories. We discuss several corollaries of our results and comment on the relation to the F-theorem.
