论文摘要
我们研究了弦理论中BPS扇区的微晶格如何在双$ u（n）$仪表理论中组织。微晶格采取了一系列麸皮和其开放/封闭的弦激励的形式。我们通过分析量规理论中的确定性操作员的修改，提出了一个全息构建字符串/勃雷配置索引的处方。字符串/Brane配置应在无张力限制中解释，但其索引在有限的$ n $下定义明确。在各种示例中，我们提供了证据表明，在文献中最近提出的巨型重力类型的总和在所有此类构型中都提供了有限的$ n $仪表理论指数。最后，我们讨论了这些微晶格如何在BPS Hilbert空间中组装，在什么情况下，麸皮可以形成结合状态以产生黑洞变性。
We study how the microstates of BPS sectors in string theory are organized in the dual $U(N)$ gauge theory. The microstates take the form of a coherent sum of stacks of branes and their open/closed string excitations. We propose a prescription to holographically construct the indices of string/brane configurations by analyzing the modifications of determinant operators in gauge theory. The string/brane configurations should be interpreted in the tensionless limit, but their indices are well-defined at finite $N$. In various examples, we provide evidence that a sum, of the giant graviton-type recently proposed in the literature, over all such configurations gives the finite $N$ gauge theory index. Finally, we discuss how these microstates assemble in the BPS Hilbert space and in what circumstances the branes can form bound states to produce black hole degeneracies.
