N=2弦振幅和Ω背景

N=2 string amplitudes and the Omega background

Ioannis Florakis, Ahmad Zein Assi

摘要:

我们回顾了最近的工作[1,2],在有效的$\mathcal{N}=2$超重力作用量的一系列高阶导数广义F项方面获得了$Ω$ -背景的实现。我们讨论背后的动机,这些耦合的识别,他们的关系Nekrasov配分函数,并将它们连接到一个世界表的方法对细化的拓扑字符串。作者在2013年9月8日至15日希腊科孚岛科孚夏季研究所“非对易场论和引力研讨会”上发表

英文摘要:

We review recent work [1, 2] on obtaining a realisation of the $Ω$-background in terms of a special series of higher-derivative generalised F-terms in the effective $\mathcal{N}=2$ supergravity action. We discuss the motivation behind the identification of these couplings, their relation to the Nekrasov partition function and connect them to a worldsheet approach towards the refined topological string. Presented by the authors at the Corfu Summer Institute 2013 "Workshop on Noncommutative Field Theory and Gravity", September 8-15, 2013 Corfu, Greece
