AI 中文摘要
我们研究IIB型超引力中新近发现的AdS₉背景。首先在更便利的坐标系下回顾这些解，借此明确计算包括全息中心荷在内的若干可观测量；随后研究由IIB轴子-伸缩子源产生的非超对称7-膜构型，得到以AdS₉背景为近视界几何的显式解析7-膜解；最后通过在横平面施加反射单值性τ→-τ̄，探讨这些7-膜解与R7-膜的关系。
英文摘要
We consider the recently found $\mathrm{AdS}_9$ backgrounds in type IIB supergravity. We start by reviewing the solutions in a more convenient set of coordinates, which allows us to explicitly compute a few relevant observables, including the holographic central charge. Subsequently, we study non-supersymmetric 7-brane configurations sourced by the IIB axio-dilaton. We find explicit analytic 7-brane solutions that possess the above $\mathrm{AdS}_9$ backgrounds as their near-horizon geometry. Finally, we discuss the relation of these 7-brane solutions to the R7 branes by imposing the reflection monodromy $τ\rightarrow -\bar τ$ in the transverse plane.
