论文摘要
我们构建了一个$ \ text {ads} _2 \ times s^3 \ times s^2 $解决方案的新家族，以IIB超级重力的解决方案，作为D1-F1-F1-F1-D3-D5-NS5-NS5-D7 Brane Brane Iterpections的接近Horizon几何形状，保留了4个Suppersymorties。我们表明，这些解决方案的子类本地与$ \ text {ads} _6 \ times s^2 \ timesσ_2$ tone type IIB超级全息图型二维SP（n）固定点理论的方案。这表明这些解决方案可以解释为此CFT内的D1-F1-D3线缺陷。关闭D7-BRANES，我们用$ \ text {sl}（2，\ mathbb {r}）$构建第二个解决方案家族，可以与$ \ text {ads} _3 \ times s^3 \ times s^3 \ times s^3 \ times s^3 $ s^3 $ scressext scressive Survice scrance scressights scressights Scripts Scripts Scripts Scripts scriptional scrational（1,00） $ \ text {ads} _7/\ mathbb {z} _k \ times s^4 $。最后，使用非亚伯t-二维，我们构建了$ \ text {ads} _2 \ times s^2 \ times s^2 $ solutions的新类别的新类，以键入IIA SuperGravity，并具有4个增压，并详细介绍其M-BYEORY来源。
We construct a new family of $\text{AdS}_2\times S^3\times S^2$ solutions to Type IIB supergravity arising as near-horizon geometries of D1-F1-D3-D5-NS5-D7 brane intersections preserving 4 supersymmetries. We show that a subclass of these solutions asymptotes locally to the $\text{AdS}_6\times S^2\times Σ_2$ solution to Type IIB supergravity holographically dual to the five dimensional Sp(N) fixed point theory. This suggests that these solutions can be interpreted as D1-F1-D3 line defects within this CFT. Switching off the D7-branes, we act with $\text{SL}(2, \mathbb{R})$ to construct a second family of solutions that can be related to an $\text{AdS}_3\times S^3\times S^3$ class of M-theory backgrounds describing surface defects within the six dimensional (1,0) SCFT dual to $\text{AdS}_7/\mathbb{Z}_k\times S^4$. Finally, using non-Abelian T-duality we construct new classes of $\text{AdS}_2\times S^2\times S^2$ solutions to Type IIA supergravity with 4 supercharges and elaborate on their M-theory origin.
