$\mathbb{C}P^2$上瞬子的模空间及其轨道折叠

Aspects of the moduli space of instantons on $\mathbb{C}P^2$ and its orbifolds

Alessandro Pini, Diego Rodriguez-Gomez

摘要:

研究了$\mathbb{C}P^2$上自对偶瞬子的模空间。这些都描述了一个ADHM样的建设,允许计算希尔伯特系列的模空间。后者已被发现是盲目的某些紧凑的方向。在本文中,我们探讨这些,发现它们对应于一个格拉斯曼,在考虑适当的ungaugings。此外,类ADHM结构可以嵌入到具有已知引力对偶的$3d$规范理论中。利用这一点,我们实现了在PDMATHAMO(部分)的瞬子模空间,同时提供进一步的证据支持$AdS_4/CFT_3$的对偶性。此外,在orbifolding,我们提供了ADHM类结构的瞬子在$\mathbb{C}P^2/\mathbb{Z}_n$以及计算其希尔伯特级数。在非轨道折叠的情况下,这些结果与$\mathbb{C}^2/\mathbb{Z}_n$上的瞬子一致。

英文摘要:

We study the moduli space of self-dual instantons on $\mathbb{C}P^2$. These are described by an ADHM-like construction which allows to compute the Hilbert series of the moduli space. The latter has been found to be blind to certain compact directions. In this paper we probe these, finding them to correspond to a Grassmanian, upon considering appropriate ungaugings. Moreover, the ADHM-like construction can be embedded into a $3d$ gauge theory with a known gravity dual. Using this, we realize in $AdS_4/CFT_3$ (part of) the instanton moduli space providing at the same time further evidence supporting the $AdS_4/CFT_3$ duality. Moreover, upon orbifolding, we provide the ADHM-like construction of instantons on $\mathbb{C}P^2/\mathbb{Z}_n$ as well as compute its Hilbert series. As in the unorbifolded case, these turn out to coincide with those for instantons on $\mathbb{C}^2/\mathbb{Z}_n$.
