摘要:

我们构造了一个一般类的(小)$\mathcal{N}=(0,4)$超共形解的M-理论的形式AdS $_3\times S^3/\mathbb{Z}_k\times \text{CY}_2$,在一个区间上叶状。这些解描述了M5-膜相交中的M-弦。$M$ -字符串支持与我们的背景相对应的$(0,4)$字符串。我们计算的中心电荷,并表明它的规模与$M$弦的总数呈线性关系。我们引入动量荷,从而允许在M(矩阵)理论的描述。在减少到IIA型,我们发现一类新的解决方案与4庞加莱超荷的形式AdS $_2\times S^3\times \text{CY}_2\times \mathcal{I}$,我们扩展到大规模IIA的情况下。我们推广我们的结构,提供一个完整的类AdS $_3$解决方案的M-理论与(0,4)超对称性和SU(2)结构。我们还构造了大质量IIA的新的$AdS_2\times S^3\times \text{M}_4\times \mathcal{I}$解,M $_4$是一个4d Kähler流形和四个Poincaré超荷.

英文摘要:

We construct a general class of (small) $\mathcal{N}=(0,4)$ superconformal solutions in M-theory of the form AdS$_3\times S^3/\mathbb{Z}_k\times \text{CY}_2$, foliated over an interval. These solutions describe M-strings in M5-brane intersections. The $M$-strings support $(0,4)$ quiver CFTs that are in correspondence with our backgrounds. We compute the central charge and show that it scales linearly with the total number of $M$-strings. We introduce momentum charge, thus allowing for a description in terms of M(atrix) theory. Upon reduction to Type IIA, we find a new class of solutions with four Poincaré supercharges of the form AdS$_2\times S^3\times \text{CY}_2\times \mathcal{I}$, that we extend to the massive IIA case. We generalise our constructions to provide a complete class of AdS$_3$ solutions to M-theory with (0,4) supersymmetry and SU(2) structure. We also construct new $AdS_2\times S^3\times \text{M}_4\times \mathcal{I}$ solutions to massive IIA, with M$_4$ a 4d Kähler manifold and four Poincaré supercharges.
