摘要我们考虑三球体上的三维 $ mathcal{N}=2 $ 超共形场论,并分析它们的自由能 F 作为背景规范和超重力场的函数。某些本地术语在这些背景领域中发挥着至关重要的作用,其中包括几个 Chern-Simons 术语。这些术语的出现阐明了 F 的许多微妙属性。这种理解使我们能够证明 F 最大化原理。它还解释了为什么通过本地化计算 F 会导致复杂的答案,尽管我们期望它在酉理论中是真实的。我们讨论了结果的几个推论,并评论了与 F 定理的关系。
A bstractWe consider three-dimensional $ mathcal{N}=2 $ superconformal field theories on a threesphere 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.
