$\boldsymbol{G_2}$瞬子代数的证据

Evidence for an Algebra of $\boldsymbol{G_2}$ Instantons

Michele Del Zotto, Jihwan Oh, Yehao Zhou

摘要:

在这个简短的说明中,我们提出了一些证据对存在一个代数的BPS $G_2$瞬子。这些都是瞬变配置,管理当地$G_2$ holonomy流形$\mathcal X$的7 D SYM理论的配分函数。为了阐明这样的结构,我们开始调查的关系与父4d $\mathcal N=1$理论得到的几何工程M-理论$\mathcal X$。本文的主要观点是证实以下的梦想:全纯部门的多中心Taub-NUT空间的理论产生了一个代数的特点组织的$G_2$瞬子配分函数。作为实现这一计划的第一步,我们通过弦对偶论证了存在着众多的几何$\mathcal X$,它们与著名的CY锥的D3膜探测所产生的四维SCFT是对偶的:所有这些模型都可以按照Dijkgraaf、Gukov、Neitzke和Vafa在拓扑M理论的背景下提出的路线进行分析。此外,我们讨论了一个有趣的关系,科斯特洛的扭曲M-理论,它产生在当地补丁,是一个关键因素,在确定相关的代数。

英文摘要:

In this short note, we present some evidence towards the existence of an algebra of BPS $G_2$ instantons. These are instantonic configurations that govern the partition functions of 7d SYM theories on local $G_2$ holonomy manifolds $\mathcal X$. To shed light on such structure, we begin investigating the relation with parent 4d $\mathcal N=1$ theories obtained by geometric engineering M-theory on $\mathcal X$. The main point of this paper is to substantiate the following dream: the holomorphic sector of such theories on multi-centered Taub-NUT spaces gives rise to an algebra whose characters organise the $G_2$ instanton partition function. As a first step towards this program, we argue by string duality that a multitude of geometries $\mathcal X$ exist that are dual to well-known 4d SCFTs arising from D3 branes probes of CY cones: all these models are amenable to analysis along the lines suggested by Dijkgraaf, Gukov, Neitzke and Vafa in the context of topological M-theory. Moreover, we discuss an interesting relation to Costello's twisted M-theory, which arises at local patches, and is a key ingredient in identifying the relevant algebras.
