论文摘要
字符串和5个桥接连接被证明可以简洁地对所有已知的8d $ {\ cal n} $ = 1字符串真空进行分类。这需要对普通$ [p，q] $ -7溴的描述的扩展，以始终包括O7 $^+$ - 飞机，然后自然地编码$ \ mathfrak {sp} _n $ gauge代数的动力学，包括其高型中心符号。该分析的核心是循环连接，即包围7型晶体和O7 $^+$的琴弦/5个玻璃。循环连接进一步指示在8D Moduli空间边界上出现的紧急9D描述的仿射对称性的出现。这样的限制重现了所有9D弦真空，包括两个断开的等级（1,1）模量组件。
String and 5-brane junctions are shown to succinctly classify all known 8d ${\cal N}$=1 string vacua. This requires an extension of the description for ordinary $[p,q]$-7-branes to consistently include O7$^+$-planes, which then naturally encodes the dynamics of $\mathfrak{sp}_n$ gauge algebras, including their higher-form center symmetries. Central to this analysis are loop junctions, i.e., strings/5-branes which encircle stacks of 7-branes and O7$^+$'s. Loop junctions further signal the appearance of affine symmetries of emergent 9d descriptions at the 8d moduli space's boundaries. Such limits reproduce all 9d string vacua, including the two disconnected rank (1,1) moduli components.
