论文摘要
我们构建了$ d = 11 $超级固定的超对称$ ads_3 $ sultions unterions $ d = $ d = 2 $，$ \ mathcal {n} =（0,2）$ scfts，与包裹两个不同的四维orbifolds包装的M5-BRANES相关。在一种情况下，Orbifold是另一个主轴上的主轴纤维，而在另一个情况下，它是旋转纤维，上面是带有$ g> 1 $的Riemann表面。我们表明，从重力溶液中计算出的$ d = 2 $ scft的中心电荷与使用异常多项式计算的场理论一致。新的$ d = 11 $解决方案是在建造新的一致的kaluza-klein截断后获得的最大$ d = 7 $测量的超级加盖超级截断的主轴降低至$ d = 5 $ d = 5 $最小的测量超级级别。
We construct supersymmetric $AdS_3$ solutions of $D=11$ supergravity, dual to $d=2$, $\mathcal{N}=(0,2)$ SCFTs, that are associated with M5-branes wrapping two different four-dimensional orbifolds. In one case the orbifold is a spindle fibred over another spindle, while in the other it is a spindle fibred over a Riemann surface with genus $g>1$. We show that the central charges of the $d=2$ SCFTs calculated from the gravity solutions agree with field theory computations using anomaly polynomials. The new $D=11$ solutions are obtained after constructing a new consistent Kaluza-Klein truncation of maximal $D=7$ gauged supergravity reduced on a spindle down to $D=5$ minimal gauged supergravity.
